To recover from a corrupted BIOS, perform the following steps:
1. Turn off the system.
2. Remove the system's case and move the jumper block on J12H1 from pins 2-3 to pins 1-2. Leave the jumper block on pins 4-5 in place.
3. Place the update diskette in drive A: and turn on the system.
4. There will be no video display during the BIOS recovery, this is due to the small amount of code available in the non-erasable boot block area.
5. After the system boots, it will beep once and the floppy drive light should light up. The system is copying the recovery code into the Flash EEPROM.
6. Just before the recovery completes, the system will beep twice. Once this occurs, watch the floppy drive light. When the light goes off, turn off the system.
7. Move the jumper block on J12H1 from pins 1-2 back to pins 2-3.
8. Turn the system on and repeat the steps for updating the BIOS.
The motherboard comes with 16KB of cache integrated in the processor ( CPU ). A secondary external cache level (write-back cache ) of 256KB is soldered on the motherboard. This cannot be upgraded.
This motherboard can accommodate any of the following CPUs.
The upgrade processor installs in the Zero Insertion Force (ZIF) socket location U2B1. Jumpers do not need to be changed.
The video memory on this system can be upgraded to 2MB, by using two 256Kx16-70ns SOJ DRAM chips.
