I am having this same problem. I have a dell D600 and am trying to
put RH7.3 on it. Install goes off without a hitch, including setting
the /boot (hda1 which is 128MB) file system type to linux (83). After
going through the install CDs it reboots only to find "Missing io.sys"
at the prompt.
When I boot from the RH7.3 disk "linux rescue", then check using
fdisk; the boot partition is set back to FAT! I even tried what I
though would overwrite the MBR dd if=/dev/null of=/dev/hda count=1
size=512 got back 0bytes in 0byes out. Then reload the entire RH7.3
Dell (who's support did NOT bawk at my wanting to use linux BTW) had
me "reset the hard drive" using a dos floppy and debug. They say
there is some kind of magic partinon in the front of the hard drive
(60GB, IDE, 9.5MM, 4.2K, FUJITSU, V40).
Here is the script that I typed in by hand at the a:>
-F 200 L1000 0
xxxx:0100 MOV AX,301
xxxx:0103 MOV BX,200
xxxx:0106 MOV CX,1
xxxx:0109 MOV DX,80
xxxx:010C INT 13
xxxx:010E INT 20
xxxx:0110 (Leave this line blank and press the <Enter> key)
This caused the next install of RH7.3 to ask if I wanted to initialize
the disk. I said "y". Again the install went off with no problem.
looking for 'io.sys'!
So why? I did not have this problem with my current Latitiued C610.
Thanks much in advance,
