Setting the CPU Speed

installing a new CPU or to change the current CPU speed. See Chapter 5 of the InterServe
800 SL System Reference for the location of jumper W12.
To set the CPU Speed:
1. If you have not done so already, power down your system and remove the cover.
2. Set the jumper on W12 as follows:
Jumper W12 Setting

3. Replace the cover, and start the system. BIOS Setup will start automatically.

W12 (store the jumper by placing it on one pin only). The CPU speed setting will no

NOTE No speed configuration is required when adding a second processor with the same speed as
the original processor. If you forget to remove jumper W12 after you save the CPU speed
and exit, the selection process repeats.

The system's BIOS can be reprogrammed using a BIOS file. You can update the BIOS by
following the steps below:
1. After loading the appropriate BIOS file from Intergraph's BBS or Web site, extract it to
a bootable MS-DOS 6.x diskette.
2. Reboot your system with the MS-DOS 6.x diskette in the floppy drive. To make sure a
clean DOS environment is loaded, press the
DOS is displayed. After the system has restarted, the cursor will display at the A:>
prompt.
