Is there some reason why I cannot get things to go with the > untranslated geometries? I had similar experiences. Since I believe BIOS *always* uses the translated geometry when booting (at least, the NCR 810 BIOS seems to), I discovered that I had to reset the geometry (in the Partition menu) to what the SCSI controller's BIOS was going to translate to or I would get the dreaded ``Missing Operating System'' response on boot. For drive-capacity <= 1GB I had success with the usual: CYLS = capacity-in-MB HEADS = 64 SECTORS = 32 For 1GB < drive-capacity <= 2GB I had success with: CYLS = capacity-in-MB/2 HEADS = 128 SECTORS = 32 -- Bob Willcox bob@luke.pmr.com (or obiwan%bob@uunet.uu.net) Austin, TX
