It all started when I tried to install 2 GB secondary HD to my
486DX-66 system which had PC-DOS 6.3 and Slackware 1.2.1 kernel Linux
in 2 seperate partitions. I did split DOS partition in two having
C:\ and D:\ and had swap partition in addition to raw linux ext2 partition
on the other hand. LILO boot manager sits on the top of all these
partition. After many trials to solve the problem of not being able to boot
to DOS from floppy and being not able to boot from HD at all, I have the
1) I now can boot to linux but not able to mount neither /dos partition
fd0 nor /dev/mcd (that is mitsumi cd-rom). I installed Linux from
CD-ROM and don't have the floppies.
2) I can now boot to DOS from PC-DOS 6.3 system floppy, but not able
to access to my C:\ drive because the media is not recognized.
Any suggestions on how to recover the DOS partition?
Any suggestions on how to reload the lilo manager and
expand linux to fill all the disk and format secondary
Thank you very much.
1) Lilo Boot manager prompts as usual "LILO Boot: ", but when DOS
is entered it does the following and stuck.
2) I can now boot to DOS from floppy disk. I booted to PC-DOS 6.3 and
setup window appeared: Hard disk partition C: is unformatted. PC-DOS
6.3 does not recognize unformatted media.
Note: D drive that is also a DOS partition is fine.
Question: Is there a third party disk utility to correct the sector
problem for the boot partition?
How can I recover my c:\ DOS partition ?
3) When booting linux, /etc/rc.d/rc.s: Testing filesystem status: Read only
file system. VFS: Cannot find a valid MSDOS filesystem on dev 0x0301
UMSDOS Beta 0.6 (compatibility level 0.4, fast MSDOS)
4) Booting linux from hard disk or floppy is fine with the following
mount -a gives; wrong fs type or bad superblock on /dev/hda1
/dev/mcd is not a valid block device
fs type /dos not supported by kernel
/dev/fd0 is not a valid block device
/dev/mcd /cdrom iso9660 ro
/dev/hda1 /dos umsdos defaults 1 1
