A single Xeon processor must always be accompanied with two Voltage Regulator Modules (VRM) inserted in the VRM sockets 1 and 2 (refer to the diagram on page 7 for the VRM sockets position on the system board). Single processor models can be upgraded to dual processor systems by installing the second processor accessory in the vacant slot. The second processor must be a Xeon processor of the same type, speed and level-2 cache memory capacity as the first. It is installed by gently inserting the processor into the vacant processor connector slot (labeled DUAL PROC [2]) until it clicks into place. Insert the VRM1 that was supplied with the second processor into the vacant third VRM socket. The following table explains how to perform supported processor upgrades.

Cache Memory

512 KB or 1 MB of level-two cache memory is integrated in the Pentium II or Pentium III Xeon processor package.

Main Memory

The PC Workstation has four DIMM slots on the system board for installing main memory; slots Mem 1, Mem 2, Mem 3 and Mem 4. Models are supplied with 128 MB of unbuffered main memory. If additional memory is required, up to 1 GB of unbuffered memory may be installed. Memory upgrades are available in single 64 MB, 128 MB or 256 MB unbuffered ECC SDRAM modules. Or, alternatively, replace the existing unbuffered memory modules and install Registered ECC SDRAM memory modules. Up to 2 GB of Registered memory modules may be installed. A serial EEPROM on each DIMM contains data on the memory speed. This information is read at each power on, and access time settings are set accordingly. NOTE: Registered ECC SDRAM memory modules are not compatible with unbuffered ECC SDRAM modules. Therefore, memory can be upgraded to a maximum of 2 GB using only multiples of 512 MB Registered ECC SDRAM modules (4 x 512 MB).

Video Memory on Kayak XU Series 04xx
The graphics controller installed on the PC Workstation could be either a Matrox Productiva G100-Quad, a Matrox Millennium G200, an AccelGalaxy AGP or an ELSA GLoria Synergy+. The Matrox Productiva G100-Quad graphics card can support a multi-monitor environment allowing for a custom-configured display solution of up to four monitors at a time with a total of 16 MB of video memory (4 MB per monitor). There are three possible configurations: horizontally, vertically, or in a square. The Matrox Millennium G200 has a 8 MB of SGRAM memory already supplied on the graphics controller board. Memory may be upgraded to a maximum of 16 MB by installing a 8 MB SGRAM memory module onto the board. The AccelGalaxy AGP Graphics card has 31 MB of video memory already supplied on the graphics controller board, which cannot be further upgraded. This card is supported only on the Windows NT operating system. Drivers do not exist for Windows 95 nor Windows 98 operating systems.

Ka_sh_1.bk Page 11 Thursday, June 15, 2000 7:27 PM
The ELSA GLoria Synergy+ includes 4 MB of installed SGRAM memory on the video board. Added to this, there is a preinstalled 4 MB SO_DIMM (SGRAM) memory module, giving a total of 8 MB, which cannot be further upgraded. No switch or jumper settings are need to be changed (all jumpers should be left in the positions in which they were set by the manufacturer).
HP VISUALIZE fx6 Hardware Accelerator
The HP Kayak XW Series 0480 contains an HP VISUALIZE fx6 graphics hardware accelerator. There is a total of 18 MB of installed Synchronous Graphics RAM (SGRAM) frame buffer on the graphics controller board.
HP VISUALIZE fx6 Texture Mapping Module An additional 32 MB of Synchronous Dynamic RAM (SDRAM) texture memory can be added by installing the texture mapping module accessory (D6795A) for the HP VISUALIZE fx6 Graphics Accelerator.
For instructions on how to install the texture memory module, refer to the HP VISUALIZE fx6 Texture Module Installation Guide which is supplied with the accessory.

Beep, POST, and Error Codes

Beep Codes

If an error occurs during the POST, which prevents the PC Workstation from starting, and before the display device has been initialized, a series of beep codes are issued. Beep codes indicate that a fatal error has occurred and can be reported one after another if there is more than one detected error. In this case, the first detected error is the most important. These codes are useful for identifying the error when the system is unable to display the error message.

B-2 Recovery Boot Active Procedures
Force BIOS flash, Switch 9 (XA models) or 10 (XW and XA-s models) Down Position
WARNING: WARNING: For Kayak XU Series 03xx, XA-s Series 02xx and XA Series 05xx, a specific Mini-Dos bootable disk has to be used. An image of this Mini-Dos bootable floppy can be obtained from the Alps/Info server (not available from the external web site). If you do not have access to the Alps/Info server, contact your escalation team.

If, for example, during a BIOS flash, the procedure is interrupted by a power failure, and the system does not restart, then you can force a BIOS flash. However, it should be noted that during the procedure, there is no image on the screen, nor access to the keyboard or mouse (only vital devices that are required to boot on the floppy device are initialized). To force a BIOS flash, do the following steps: 1 Ensure that you have created a DOS-bootable diskette. This floppy diskette contains all the recovery and system BIOS programming software (phlash.exe, platform.bin and hb1xxxyy.Ful). Include the flash command in the autoexec.bat, for example: phlash /mode=3 hb1xxxyy.Ful Turn off the computer. Set Switch 9 (XA models) or, Set Switch 10 (XW, XU and XA-s models) to the DOWN position (=on). Insert the DOS-bootable diskette (refer to the above warning). Power on the computer. During the recovery process, short beeps are emitted. The recovery process is finished when there is a much longer beep (approximately around 1 to 2 minutes). Power off the computer. Press the power ON/OFF button (for about 5 seconds), until the ON/OFF light switches off. Set the switch 10 to the UP position (=off).

Disk Striping

To achieve top performance through disk striping, a RAIDport is provided on the system board aligned with PCI socket 3. When the Adaptec FastRAID2 accessory is installed in the PCI socket and RAIDport, the adapter sets up and accelerates disk striping on hard disks connected to the internal UltraWide 16-bit SCSI controller. The Adaptec RAIDport adapter should be used with one or more stripped hard disks. For more information, refer to the HP FastRAID Installation and Configuration Guide that came with your FastRAID2 accessory.
Before Installing an IDE Hard Disk Before Installing a SCSI Hard Disk
Refer to the drives installation guide to see if you must set jumpers or if there is a special installation procedure to follow. If you are installing an additional SCSI drive, you should assign an unused SCSI ID to this accessory. SCSI IDs range from 0 to 6 for Ultra narrow 8-bit SCSI and from 0 to 15 for Ultra wide 16-bit SCSI. SCSI ID 0 is used by the first SCSI hard disk drive and SCSI ID 7 is reserved for the integrated SCSI controller (the default for narrow and wide SCSI devices). Depending on your operating system, you may need to set a SCSI ID for Plug and Play devices (SCSI devices that support the SCAM protocol). If HP FastRAID is installed, you will need to set a SCSI ID. You should assign an unused SCSI ID to the second SCSI hard disk drive (for example, SCSI ID 1). The SCSI ID is usually configured with jumpers on the SCSI hard disk drive. Refer to the installation guide supplied with the drive for information on selecting a SCSI ID. Some internal SCSI disk drives may have termination resistors that must be removed or disabled before installation in your computer. Refer to the drives installation guide for more details and to see if there is a special installation procedure to follow.
