My new hard drive is up and working with linux; I was able to do it without a reinstall. Really pretty easy once you figure it out the first time. We have now moved my dos hard drive to hdb (it was hdd before). I was hoping not to have to boot in from floppy any more, but to use lilo as I did when I had a windows os on hdb. I can boot in with a floppy, and I can mount hdb1 and it is my dos hard drive. Both linux cfdisk and dos fdisk show it as bootable. I've also used map-drive to switch the drives, but it still won't boot. Not a huge problem, as I can go on booting from floppy to dos as before, but I would like to know why this won't work. The relevant part of my lilo.conf is included below. Thanks. Cheryl other=/dev/hdb1 table=/dev/hdb label=dos # restricted alias=3 map-drive = 0x80 to = 0x81 map-drive = 0x81 to = 0x80
