My problem is that booting from the hard disc gets LI but not LO, i.e. LILO isn't mounting linux. Two people (many thanks) suggested I instruct lilo to use linear addressing either by using the lilo -l option or putting "linear" into /etc/lilo.conf. This sounds very promising but I think the way that changing from a dawicontrol (ncr) to the Adaptec 2940U changes the perceived geometry is more serious than this. After booting in rescue mode from the resc1440.bin floppy lilo (with or without linear mode) returns:
Device 0x0800: Invalid partition table, 1st entry 3D address: 1/1/0 (32) Linear address: 30/1/0 (61) -v shows it's reading /dev/sda1 (correct) for that error message so I seem to be caught in a bind that the resc floppy can mount the drive but the geometry has been changed so fundamentally I can't rewrite the bootable version of linux in a way that lilo will use. I'm back to you all again. Any suggestions? (The old controller is happily running another machine miles away and I can't find another like it around and I'd hate to ditch the money I spent on the Adaptec so ... yes, ... I too would like to do the sensible thing but can't !!) TIA, Chris Chris Evans, R&D Consultant, Tavistock & Portman NHS Trust
