FC2 installed well and everything seemed to work -- I thought. I noticed that my floppy drive doesn't work. I'replaced the drive and cable with new parts then reinstalled FC2. The BIOS will boot a DOS floppy, and a RH9 boot floppy created from on an XP machine. Attempts to mount the floppy manually yield "invalid block device". I am working my way through Michael Jang's RHCE ver8 study guide. but it doesn't offer much help with this. I had RH9 on this machine and the original drive worked fine. Any suggestions? I think that having 3 devices share IRQ 10 seems funny, but one thing at a time. Thank you.
