tests. Check to see that the drive is defined with the proper
diskette type in Setup and that the diskette drive is attached
correctly.

boards, check the cache jumpers. You may have to replace
the cache. See your dealer. A disabled cache slows system
performance considerably.
CPU socket number for Multi-Processor error.
ServerBIOS2 test error: Cannot write to EISA CMOS.
ServerBIOS2 test error: Cannot write to extended DMA
(Direct Memory Access) registers.
ServerBIOS2 test error: Cannot generate software NMI
(Non-Maskable Interrupt).
ServerBIOS2 test error: Fail-Safe Timer takes too long.
Address conflict for specified device.
Run ISA or EISA Configuration Utility to resolve resource
conflict for the specified device.
The hex number nnnn is a map of the bits at the RAM
address which failed the memory test. Each 1 (one) in the
map indicates a failed bit. See errors 230, 231, or 232 above
for offset address of the failure in System, Extended, or
Shadow memory.
