When using an ls120 drive as the boot drive, install for ftp fails when looking for the second disk in the two disk set. with this setup /dev/hda -- 4 gig drive /dev/hdb -- ls120 drive /dev/hdc -- cdrom drive no floppy drive when the system prompts you to insert the second install disk, it errors out looking for /dev/fd0 and hangs.
Currently loading of the second install disk is not supported for the LS120 drives. You will need to use a standard floppy device or install from a cdrom. Also NFS installs do not require a second disk so that may be better if you are wanting to install over the network.
