It is nice that MSDOS looks at the drives as 1 and 2, and Xenix 0 and 1. What disk you want to format? ...1.... ARGGGGGG! Goodbye spool partition and root system! Now that I broadcast my stupidity, on with the problem: I tried to get the two controllers working, and I did, somewhat. The two controllers are a WD-1006-WAH and a WD-1006VMM1. The 10006VMM1 is the one I am running int. 14, standard address, and works fine. The WD-1006WAH is the one I did the mod on for int. 14, and address change 0x170. On boot the second controller shows up at its proper address, and mounts after it does a seekout. The drives are all Miniscribe 6085 72 meg, 28 ms drives. The problem occurs sporatically. If I access the drive it may/maynot be ready. It does that seekout and then reads the data fine. Western Digitals Guru's said it may be the Miniscribe drive going to sleep when it is not selected, and to change the jumpers to disable autopark. The only jumber on the drive is drive select, and besides the heads are not parking. SCO says, hum.. sounds like a hardware problem, sorry. According to WD, neither of the boards have ROM BIOS. They did say that the older WD-1006 may be giving me trouble, but all this info is pretty sketchy. I ordered an Adaptec ACB2310 whih allows jumper controlled interrupt and address modifications to replace the 1006-WAH in an attempt to rectify the problem, but I am just stabbing in the dark. Any help out there, please? -- Adelphi University, Garden City, NY 11530 (516) 663-1170 Department of Mathematics and Computer Science markd@adelphi.UUCP or mark@promark.UUCP UUCP: ...philabs!sbcs!bnlux0!adelphi!markd
