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.
Problem with NVRAM (CMOS) data.
I/O device IRQ conflict error.
There was not enough room in the IPL table to display all
installed I2O block-storage devices.
Verify the following: The hard disk drive is correctly
installed. A startable diskette is in the diskette drive. If you
still see the same error message, check the boot sequence
using BIOS Utility.
Parity error found in the system bus. BIOS attempts to locate
the address and display i on the screen. If it cannot locate the
address, it displays ????. Parity is a method for checking
errors in binary data. A parity error indicates that some data
has been corrupted.
