Floppy 3 mode refers to a 3.5-inch diskette with a capacity of 1.2 MB. Floppy 3 mode is sometimes used in Japan. This item specifies the type of video card in use. The default setting is VGA/EGA. Since current PCs use VGA only, this function is almost useless and may be disregarded in the future. This parameter enables you to control the system stops in case of Power On Self Test errors (POST).

Base Memory
Refers to the option of memory that is available to standard DOS programs. DOS systems have an address space od 1MB, but the top 384KB (called high memory) is reserved for system use. This leaves 640 KB of conventional memory. Everything above 1MB is either extended or extended memory. Memory above and beyond the standard 1MB of base memory that DOS supports. Extended memory is only available in PCs with an Intel 80286 or later microprocessor. Extended memory is not configured in any special manner and is therefore unavailable to most DOS programs. However, MS Windows and OS/2 can use extended memory. Total based and extended memory, and I/O ROM 384KB available to the system.

Advanced Chipset Features
The advanced chipset features setup option is used to change the values of the chipset registers. These registers control most of the system options in the computer. NOTE: Change these settings only if you are familiar with the chipset.

Parameter Current CPU Frequency Current DRAM Frequency DRAM Timing Control
Description Detect the current CPU Frequency Detect the current DRAM Frequency Enables you to select the CAS latency time in HCLKs of 2, 2.5, or 3. The value is set at the factory depending on the DRAM installed. Do not change the values in this field unless you change specifications of the installed DRAM or the installed CPU. This item controls the timing delay (in clock cycles) before the DRAM starts a read command after receiving it. This item allows you to set the amount of time a RAS can be kept open for multiple accesses. High figures will improve performance. This is the duration of the time interval during which the Row Address Strobe signal to a DRAM is held low during normal Read and Write Cycles. This is the munimum interval between completing one read or write and starting another from the same (non-page mode) DRAM. Techniques such as memory interleaving, or use of Page Mode DRAM are often used to avoid this delay. Some chipsets require this parameter in order to set up the memory configuration properly. The RAS Precharge value is typically about the same as the RAM Access (data read/write) time. This is the amount of time a CAS is performed after a RAS. This lower the better, but some DRAM does not support low figures.

Troubleshooting
This chapter provides troubleshooting information for the Aspire SA80/AcerPower S280 Power-On Self-Test (POST) POST Check Points POST Error Messages List Error Symptoms List
Power-On Self-Test (POST)
Before the computer can be used, all the components must be tested and initialized, and the operating system must be bootstrapped into memory. This process is know as the power-on Self test(POST), generally under the control of the BIOS. The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the system components, and controls the operation of the power-on password option. During POST, system reports test or initialization failure through Beep codes, display error messages on screen(if available), or LED. The system halts when fatal error occurs. The main components on the main board that must be diagnosed and/or initialized by POST to ensure system functionality are as follows: Microprocessor with built-in numeric co-processor and cache memory subsystem Direct Memory Access (DMA) controller Interrupt system Three programmable timers ROM subsystem RAM subsystem RTC RAM subsystem and real time clock/calendar with battery backup Onboard serial interface controller Onboard parallel interface controller Embedded hard disk interface and one diskette drive interface Keyboard and auxiliary device controllers I/O ports PS/2-compatible mouse port PS/2-compatible keyboard port Serial ports Parallel ports USB port

POST Check Points

When POST executes a task, it uses a series of preset numbers called check point to be latched at port 80h, indicating the stages it is currently running. This latch can be read and shown on a debug board. The following table describes the Acer common tasks carried out by POST. A unique check point number represents each task.
