Hello all, I wrote earlier about getting errors when loading Linux's
root image from floppy (the boot sequence seems to go okay).
A few people suggested re-trying with brand new floppy disks;
apparently the bootstrap sequence can't recover from a bad sector. I
tried this and got the same error.
If anyone has seen this before, with the solution being something
other than a bad disk, I would appreciate any assistance.
A copy of my original post follows.
Thanks,
Fred

wonderful new IBM PS/2 Model 25-386sx machine. Wait, don't shoot me
yet, this IBM has the standard AT bus architecture! It also has 1.44
Mbyte floppy drive and 4 megs of RAM.
I'm using the 0.97 versions which I rawrote to floppies on this
machine. Using the boot disk, things were going okay:
serial port at 0x03f8 (irq = 4) is a 16450
8 virtual consoles
4 pty's
lp_init: lp0 exists (0)
No bus mouse detected.
Linux version 0.97-11 Aug 1 1992 13:33:18
Floppy drive(s): fd0 is 1.44M
floppy: FDC version 0x90
sock_init: initializing family 1 (AF_UNIX)
scsi : 0 hosts.
scsi : detected 0 SCSI disks 0 tapes total.
insert root floppy and press ENTER
But then I inserted the root floppy, pressed ENTER, and things went
bad:
floppy I/O error
dev 021c, sector 0
floppy I/O error
dev 021c, sector 2
bread failed
floppy I/O error
dev 021c, sector 2
bread failed
floppy I/O error
dev 021c, sector 0
MSDOS bread failed
Kernel panic: Unable to mount root
I tried rawriting the root disk again and tried the whole process over
a few times with the same result each time.
If anyone has any ideas, please post or e-mail to me. Thank you.
