Doug White responded: Not again :( This problem came up a few weeks ago... I'm sorry to say that it is back, and I'd call it a bug. I'm not sure if someone with two SCSI disks would have this problem; I'll have to try that experiment on another machine. ... It's starting to roll through the mail archives, so some time spent there might coax it into releasing the eventual solution. I spent a while searching the archives and didn't turn it up, but perhaps I didn't choose the right keywords to search on. Specifically giving the boot partition to the Boot: prompt (ie, "sd(0,a)/kernel") should work. I'm guessing the bootblocks may be getting confused by your IDE disks. Bravo! The kernel duely informed me that the syntax to force it to use the BIOS device 1 (i.e, the SCSI disk in a two disk IDE + SCSI computer) is: 1:sd(0,a)kernel And this works. Thanks very much for the quick and helpful response. -- James Leinweber State Laboratory of Hygiene <jiml@slh.wisc.edu> University of Wisconsin Madison WI, USA +1 608 262 0736
