Help! once again. The following problem:
12 MHZ IBM AT Compatible, AT-339 motherboard.
Western Digital WD1002-WA2 disk controller board
Miniscribe 3425 hard disk (20 Meg, 615 cyl 4 heads)
Award BIOS 3.01B (80286 support)
What happens is when it is powered up, the drive spins up,
and I get ERROR INITIALIZING HARD DISK 0 after about 20 seconds
of waiting with the select light on. The drive is perfectly fine
on other machines.
Two questions:
1 -On the drive, what are the meanings of the 8 dip
switch settings?
2 - In the CMOS configuation RAM, is the drive type 2 or type
6?? Difference is in "compensation" value (300 vs FFFF)
Other than that, if anyone knows of an archive of hardware diagnostic
software, I would really appreciate it if you could tell me where.
Thanks ...

The drive is perfectly fine > on other machines. One suggestion: Take a look at the drive cables in the machine that doesn't work along with a set in a machine that does work. The wider of the 2 cables may have a section of the cable twisted at the connector. If the two cables (working and non-working) are not the same in this respect, then the drive select jumper or switch on the drive is not set properly. The controller that you are using only recognizes 2 drives (0 and 1). A switch or jumper controls this on the drive. The 'cut and flip' in the cable reverses the interpretation of this switch. Most cables that support 2 drives have one flipped and one straight through, so that both drives use (the default) DS1. Bill Kuykendall ...ddsw1!point!wek
