The start should be set to 0. If at all possible we should use the Geomtry specified by the BIOS, and only fall back to the above if we can't seem to get it. Furthermore I think we should change the compiled into boot1 MBR table to use the absolute minimal and maximal values for start and end addresses, both in the size/start fields and in the CHS fields. This insures data protection from the likes of Win95 and other obnoxious installation programs. I need to go look at the current sysinstall program and see just what it is doing when I feed it values like 1024/1/1 for the disk geometry, if it is setting start=0 and size=1024 this would be a really bad situation, if it picks up my size from the disklabel, then great, nothing should need to change in that code. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation, Inc.
