AST PREMIUM 486/33 WITH SQL SERVER
|
|
|
|
|
|
PROBLEM: SQL Server version 4.2 hangs during installation or log-on
|
|
while using the system administrators facility (SAF) with a
|
|
486DX processor card. This error occurs either in an ISA or
|
|
EISA system.
|
|
|
|
CAUSE: The problem has been isolated to the current version of BIOS.
|
|
If CMOS byte 41, bit 4 is high (co-processor disabled), SQL
|
|
Administrator will hang.
|
|
|
|
AFFECTED
|
|
SYSTEMS: 486DX/25 or 33 ISA or EISA.
|
|
|
|
SOLUTION: The following are two solutions available until a new version
|
|
of BIOS is released:
|
|
|
|
1) Using Debug type in the following instructions to determine
|
|
the status of the byte 41:
|
|
|
|
o 70 41 ;point to byte 41
|
|
i 71 ;get the byte
|
|
|
|
Then adjust the value so that bit 4 is low (example: F8h
|
|
becomes E8h). Write the new value back to CMOS using the
|
|
following instructions:
|
|
|
|
o 70 41 ;point to the byte
|
|
o 71 xx ;xx=new value in hex
|
|
|
|
2) Temporarily install a 386DX or SX processor board. Boot and
|
|
go into setup. Tab down to the field for Enable/Disable
|
|
Co-processor. Set to enable. Save and exit. Then,
|
|
reinstall the 486 processor board.
