If you go through the corrective steps above and still receive an error message, the cause may be an equipment malfunction. If you are sure that your configuration values are correct and your battery is in good condition, the problem may lie in a damaged or defective chip. In either case, contact an authorized service center for assistance.
Chapter 2 System Board 2-29
Most systems are already configured by the manufacturer or the dealer. There is no need to run Setup when starting the computer unless you get a Run Setup message. The Setup program loads configuration values into the battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM.
If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system cannot retain configuration values in CMOS. Ask a qualified technician for assistance.

Hard Disk Block Mode

This function enhances disk performance depending on the hard disk in use. If you set this parameter to Auto, the BIOS utility automatically detects if the installed hard disk drive supports the Block Mode function. If supported, it allows data transfer in block (multiple sectors) at a rate of 256 bytes per cycle. To disregard the feature, change the setting to Disabled.

Advanced PIO Mode

When set to Auto, the BIOS utility automatically detects if the installed hard disk supports the function. If supported, it allows for faster data recovery and read/write timing that reduces hard disk activity time. This results in better hard disk performance. To disregard the feature, change the setting to Disabled.
Hard Disk Size > 504 MB

When set to Auto, the BIOS utility automatically detects if the installed hard disk supports the function. If supported, it allows you to use a hard disk with a capacity of more than 504 MB. This is made possible through the Logical Block Address (LBA) mode translation. However, enhanced IDE feature works only under DOS, Windows 3.x, and Windows 95/98 environments. Other operating systems require this parameter to be set to Disabled.
3-14 Altos 1100E Series Users Guide

Hard Disk 32-bit Access

Enabling this parameter improves system performance by allowing the use of the 32-bit hard disk access. This enhanced IDE feature works only under DOS, Windows 3.x, Windows 95/98, and Novell NetWare. If your software or hard disk does not support this function, set this parameter to Disabled.

CD-ROM Drive DMA Mode

This parameter allows you to enable or disable the CD-ROM drive DMA mode. Set this parameter to Enabled to enable the DMA mode for the CD-ROM drive. This improves the system performance since it allows direct memory access to the CD-ROM. To deactivate the function, set the parameter to Disabled.

Enable this item if you want to specify modem activity as your system wakeup event. This means that any modem activity detected will wake up the system.
Chapter 3 - BIOS Utility 3-17

Startup Configuration

The Startup Configuration allows you to specify your preferred setting for bootup. The following screen appears if you select the Startup Configuration option from the main menu:
Fast POST Mode.. Silent Boot.. Num Lock After Boot.. Memory Test.. Release All Blocked Memory.
[Auto ] [Disabled ] [Enabled ] [Disabled] [Disabled]
Initialize SCSI Before IDE. [Disabled] System Boot Drive.. [Drive A Then C] Boot from IDE CD-ROM. [Enabled]

Fast POST Mode

This parameter allows the system to boot faster by skipping some POST routines. The default setting is Auto.
3-18 Altos 1100E Series Users Guide

Silent Boot

This parameter enables or disables the Silent Boot function. When set to Enabled, BIOS is in graphical mode and displays only an identification logo during POST and while booting, after which the screen displays the operating system prompt (such as DOS) or logo (such as Windows 95). If any error occurs while booting, the system automatically switches to text mode. Even if your setting is Enabled, you may also switch to text mode while booting by pressing after you hear a beep that indicates activation of the keyboard. When set to Disabled, BIOS is in conventional text mode where you see system initialization details on the screen.

Num Lock After Boot

This parameter allows you to activate the Num Lock function upon booting. The default setting is Enabled.

Memory Test

When set to Enabled, this parameter allows the system to perform a RAM test during the POST routine. When set to Disabled, the system detects only the memory size and bypasses the test routine. The default setting is Disabled.
Initialize SCSI Before IDE
Enabling this parameter allows SCSI devices installed in the system to be initialized before IDE devices. You may enable this parameter if you have a SCSI boot drive. When this parameter is disabled, the IDE drives are normally initialized first during POST. The default setting is Enabled.
Chapter 3 - BIOS Utility 3-19

System Boot Drive

This parameter allows you to specify the system search sequence. The selections are:
Drive A then C: The system checks drive A first. If there is a diskette in the drive, the system boots from drive A. Otherwise, it boots from drive C:. Drive C then A: The system checks drive C first. If there is a hard disk (drive C) installed, the system boots from drive C. Otherwise, it boots from drive A. C: The system always boots from drive C. A: The system always boots from drive A.

This option allows communication between all devices (lower 8-bit or upper 8-bit) on the wide (16-bit) SCSI bus. When set to yes, each device can connect on the bus. When set to no (disabled), communication can only occur on the lower 8-bits of the 16-bit SCSI bus. The default setting is yes.

Send Start Unit Command

This option, which is supported by some SCSI devices, determines whether the Start Unit Command (SCSI command 1B) is sent to the SCSI device (most devices do not require this). Enabling this option reduces the load on your computer's power supply by allowing the SCSI controller to power-up SCSI devices one-at-atime when you boot your computer. Otherwise, the devices all power-up at the same time. Most devices require you to set a jumper before they can respond to this command. When set to yes, the Start Unit Command is sent to the SCSI device during bootup. When set to no, each SCSI device powers-up in its normal fashion. The default setting is no.
The Send Start Unit Command setting is valid only if the host adapter BIOS is enabled.
If this option is enabled for more than one SCSI device, the Start Unit Command is sent first to the device with the lowest SCSI ID. When this device responds to the SCSI controller, the Start Unit Command is sent to the next highest SCSI ID with a setting of yes. The process continues until all supported devices respond to the SCSI controller. If many drives are set to yes for Send Start Unit Command, the boot time varies depending on how long it takes each drive to spin up.

You can press Esc at any time to abort the Verify Disk Media utility.
Configuring Multiple SCSI Controllers
The AHA-3950U2B SCSI controller is used as an example in the following discussion.
To use multiple PCI SCSI controllers, do the following: Install the boot SCSI controller in the lowest PCI Device number. The Device number is determined by the slot number on the PCI bus. To find out the Device number of the AHA-3950U2B SCSI controller(s), run the SCSISelect utility (by pressing the key combination Ctrl + A when it is displayed onscreen at bootup). Look on the first screen of SCSISelect in the upper right hand corner for Bus:Device xx:xxh (given in hex). If the Device number is high, move the AHA-3950U2B to a PCI slot at the other end of the motherboard and rerun SCSISelect to see if the number is lower. This step is a recommended solution for most PCI motherboards. You can also simply switch the AHA-3950U2B SCSI controller into another PCI slot if the boot order is not what is desired. If you are booting from the AHA-3950U2B and using ISA/EISA-based host adapters as secondary devices, you must disable the BIOS on all ISA/EISAbased SCSI controllers. If you are booting from ISA/EISA-based SCSI controllers and using the AHA3950U2B as a secondary device, see your ISA/EISA-based SCSI controller documentation to ensure the SCSI controller is at the lowest BIOS base address. ISA/EISA-based SCSI controllers which have their BIOS enabled boot before the AHA-3950U2B.
Chapter 4 SCSISelect Configuration Utility 4-21
SCSI Troubleshooting Checklist
The AHA-3950UB SCSI controller has been tested for compatibility with a wide range of SCSI devices. Most problems that occur during installation result from errors in preparing and connecting devices on the SCSI bus. Answer these questions first if a problem occurs during installation: Are the power cables and SCSI interface cables properly connected? Connect internal SCSI devices to your computer's power supply. Connect the power cables of external SCSI devices to a grounded line power outlet. Follow the instructions in the computer and SCSI device documentation. Is pin-1 orientation maintained throughout the SCSI bus? Are the PCI bus and slot parameters set correctly in your computer's Setup program? The PCI bus is designed to assign IRQ, port address, and BIOS address settings automatically to the SCSI controller. But you may need to assign some of these values manually in the Setup program. Is each SCSI device, including the SCSI controller, set to a unique SCSI ID? Is SCSI termination set correctly? If your problem is still not resolved, continue with the next section.

BIOS Startup Messages

After you have configured your SCSI controller, the SCSI controller BIOS displays a message when you boot your computer. Normally, this message lists the SCSI ID, manufacturer, model number and other information for each SCSI device that the BIOS detects. If an initialization failure occurs, however, the SCSI controller BIOS displays a specific error message followed by a BIOS Installation Failure message. Here are some of these error messages and their meaning:
WARNING!!! A drive larger than 1 gigabyte has been detected with 64 head / 32 sector partitioning. This drive is not compatible with the 255 head / 63 sector translation which has been enabled on this adapter. Data could be corrupted! Please check your system setup! Press any key to continue.
This message occurs only if Extended BIOS Translation is enabled in the SCSISelect utility. It means that the BIOS detected a large capacity drive with invalid partition information in the master boot record. If you are using a drive larger than 1 GByte under MS-DOS 5.0 or above and this message appears, do the following: 1. Run the SCSISelect utility and set Extended BIOS Translation to Disabled. (See Extended BIOS Translation for DOS Drives > 1 GByte in the Advanced Configuration Options section). Exit from the SCSISelect utility and back up the data on the disk drive, if you want to save it.
Chapter 4 SCSISelect Configuration Utility 4-23
Perform a SCSI low-level format with the Format Disk utility under SCSI Disk Utilities in the SCSISelect utility.
All data on the target drive will be lost when you run the Format Disk utility. Back up your data before you run it! 4. 5. 6. In the SCSISelect Advanced Configuration Options menu, set Extended BIOS Translation to Enabled. Partition the drive again. Restore data to the drive, if necessary.
Device connected, but not ready
This message appears if the SCSI controller receives no answer when it requests data from an installed SCSI device. The SCSI controller skips this device and moves on to the next device on the bus. Do the following if you see this message when you request data from a SCSI drive: 1. 2. 3. Run the SCSISelect utility and access SCSI Device Configuration. Locate the host controller's SCSI ID and set Send Start Unit Command to yes. Exit the SCSISelect utility and request data from the drive again. If the message still appears, follow the drive manufacturer's instructions to make sure the drive is set to spin-up when the power is switched ON.

Memory Upgrade

The three 168-pin sockets onboard supports SDRAM-type DIMMs only. You may install 16-MB, 32-MB, 64-MB, or 128-MB DIMMs for a maximum 384-MB system memory. The SDRAM DIMMs should work under 3.3 volts; 5-volt memory devices are not supported. Memory modules with a timing setting of 66 MHz are defined under unbuffered DIMM specifications, while 100 MHz modules are defined under Intel PC-100 SDRAM specifications. Do not use both 66 MHz (unbuffered) and 100 MHz (registered) SDRAM together. This might cause your system to malfunction.
Each of the sockets represents one independent bank. This allows you to install DIMMs with different capacities to form a configuration.

Memory Configurations

Installing a DIMM

To install a DIMM, align it with the socket and press it down until the holding clips secure the DIMM in place. The DIMM socket is slotted to ensure proper installation. If you slip in a DIMM but it does not completely fit, you may have inserted it the wrong way. Reverse the orientation of the DIMM.

Removing a DIMM

To remove a DIMM, press the holding clips on both sides of the socket outward to release the DIMM. Place your forefingers on the top of the DIMM before you press the holding clips to gently disengage the DIMM from the socket.

Reconfiguring the System

Reconfigure the system after installing or removing DIMMs. Follow these steps to reconfigure the system: 1. 2. 3. Reboot the system. A memory error message appears, indicating that the total memory does not match the value stored in CMOS. Press + +.
Press twice to exit Setup and reboot the system. The system boots with the new memory configuration.

Correcting Error Conditions
As a general rule, if an error message says "Press F1 to continue," it is caused by a configuration problem, which can be easily corrected. An equipment malfunction is more likely to cause a fatal error, i.e., an error that causes complete system failure. Here are some corrective measures for error conditions: 1. Run Setup. You must know the correct configuration values for your system before you enter Setup, which is why you should write them down when the system is correctly configured. An incorrect configuration is a major cause of power-on error messages, especially for a new system. Remove the system cover, following the directions in the housing installation manual. Check that the jumpers on the system board and any expansion boards are set correctly. If you cannot access a new disk, it may be because your disk is not properly formatted. Format the disk first using the FDISK and FORMAT commands. Check that all connectors and boards are secure.

If you go through these steps and still receive an error message, the cause may be an equipment malfunction.
If you are sure that your configuration values are correct and your battery is in good condition, the problem may lie in a damaged or defective chip. In either case, contact an authorized service center for assistance.
Most systems are already configured by the manufacturer or the dealer. There is no need to run Setup when starting the computer unless you get a Run Setup message. The Setup program loads configuration values into the battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM. If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system cannot retain configuration values in CMOS. Ask a qualified technician for assistance.
Before you run Setup, make sure that you have saved all open files. The system reboots immediately after you exit Setup.

Entering Setup

To enter Setup, + +. simultaneously press the key combination
You must press + + while the system is booting. This key combination does not work during any other time.

Serial Port 2

This parameter shows the serial port 2 address and IRQ setting.

Parallel Port

This parameter shows the parallel port address and IRQ setting.

PS/2 Mouse

The BIOS utility automatically detects if there is a pointing device connected to your system. If there is, this parameter displays the Installed setting. Otherwise, this is set to None.

Product Information

The Product Information contains the general data about the system, such as the product name, serial number, BIOS version, etc. This information is necessary for troubleshooting (may be required when asking for technical support). The following figure shows how the Product Information screen appears:
Product Information Product Name..xxxxxxxxx System S/N..xxxxxxxxx Main Board ID.xxxxxxxxx Main Board S/N.xxxxxxxxx System BIOS Version..v3.1 DMI BIOS Version..2.00.1

Onboard LAN

When you set the PCI IRQ Setting parameter to Auto, this parameter specifies the auto-assigned interrupt for the onboard LAN. If you set the PCI IRQ Setting parameter to Manual, you need to specify the interrupt that you want to assign for the onboard LAN installed in your system.
This item shows the assigned interrupt for the onboard accelerated graphics port (AGP) controller. PCI IRQ Sharing Setting this parameter to Yes allows you to assign the same IRQ to two different devices. To disable the feature, select No. If there are no IRQs available to assign for the remaining device function, we recommend that you enable this parameter. VGA Palette Snoop This parameter permits you to use the palette snooping feature if you installed more than one VGA card in the system. The VGA palette snoop function allows the control palette register (CPR) to manage and update the VGA RAM DAC (Digital Analog Converter, a color data storage) of each VGA card installed in the system. The snooping process lets the CPR send a signal to all the VGA cards so that they can update their individual RAM DACs. The signal goes through the cards continuously until all RAM DAC data has been updated. This allows the display of multiple images on the screen.
Some VGA cards have required settings for this feature. Check your VGA card manual before setting this parameter. Graphics Aperture Size This parameter determines the effective size of the graphics aperture. Graphics aperture is the address range that the AGP video and the CPU use to manage graphical objects. The lowest setting is 8 MB and the highest is 256 MB. Plug and Play OS When this parameter is set to Yes, BIOS initializes only PnP boot devices such as SCSI cards. When set to No, BIOS initializes all PnP boot and non-boot devices such as sound cards. Set this parameter to Yes only if your operating system is Windows 95.
Reset Resource Assignments Set this parameter to Yes to avoid IRQ conflict when installing non-PnP or PnP ISA cards. This clears all resource assignments and allows BIOS to reassign resources to all installed PnP devices the next time the system boots. After clearing the resource data, the parameter resets to No.

CPU Frequency

This parameter displays your CPUs speed and bus frequency. It also allows you to specify the voltage setting for your current CPU. Selecting this option displays the following screen:

CPU Frequency Bus Frequency. 66/100 MHz CPU Multiple.. [3] Processor Speed. xxx MHz
Bus Frequency The bus frequency refers to the speed by which data is transferred between internal computer components and the CPU or the main memory of the CPU. A fast bus allows data to be transferred faster, which makes applications run faster. CPU Multiple This parameter sets the Core/bus ratio of your system. The clock speed of the bus does not necessarily equal the CPUs (core). The bus clock speed is often slower than the CPU clock speed. Processor Speed The processor speed is the speed at which a microprocessor executes instructions. Clock speeds are expressed in megahertz (MHz), with 1 MHz being equal to 1 million cycles per second. The faster the clock, the more instructions the CPU can execute per second.
