I know I have a disk geometry problem because I get the "Missing Operating System" message. I mucked around with the geometry because I wanted to max. the usage of the blocks. The geometry which sysinstall assigned wasted about 5M of disk space. I am running a AMI bios 486 with a 1G scsi drive using the Adaptec VESA 284X controller. I tried to max the blocks by using a geometry with 1 head, 63 sectors and some very high cylinder number. I though this was possible because SCSI allows you to map the drive however you wish. However this does not seem to work. Even though I am using an ADAPTEC controller which has its own bios. Am I still contrained by some parameters? Eg. Boot partition within 1024 cylinders. 64 sector max. 17 head max. or anyting like that?
