Equity le - Early ROM BIOS Problem with Miniscribe 8425F
Date:
10/10/90
Page(s): 1 of 1
A problem has been reported in the Equity le when using ROM BIOS versions earlier
than release 1.76. This version has been used in production units since September
1989. The Miniscribe 8425F hard disk drive may generate a "1701" error message
when a cold boot (power switch OFF and ON) after a warm boot (software reset or
pushing the reset switch) is executed.
When the warm boot is executed, BIOS writes the status of the warm boot to the
ROM BIOS scratch register. When a cold boot is executed after a warm boot, BIOS
should erase the status in the scratch register, however, the early BIOS does not
erase the status. The BIOS reads it as a warm boot and executes the POD, skipping
the video check and the RAM check and checking the hard disk directory. This
happens too fast for the Miniscribe 8425F hard disk drive to get ready for the BIOS
check, so it shows the "1701 error message. In the case of the warm boot only, the
hard disk is already ready, so no error message is generated.
lf this problem is encountered, run the ROMBIOS program and check the ROM BIOS
version to determine if the system needs the current version of BIOS release 1.76.
Please refer to ECN No. EQIE-005, dated 9/15/89, which described the EQUlTY le
ROM BIOS release 1.76 (CMTR-A06, -B06).
