- So, unfortunately for me, the consensus of these replies seems to be that
- it is a hardware problem. I am using a Micronics i486 33 MHz EISA mother-
- board with a Phonix BIOS and OS/2 2.0 with the Service Pack installed.
- Just as someone above has guessed, both floppy drives are TEAC, the 5.25"
- being FD-55GFR and the 3.5" being FD-235HF. As far as I can tell, the
- controller (IDE) is a cheapo, noname, Taiwanese board. Having found all
- this out, I am now thinking of upgrading these to something more flexible.
- Also, while I'm at it, I am thinking of going all the way to the new 2.88 MB
- format. Could anyone suggest possible alternatives ? Which controllers,
- floppy drives, etc. work best with OS/2 ? My HD is a 200 MB Maxtor which
- thus far (knock on wood) has been working very quietly and reliably.
-
- Before I start dropping major $$$, some sugegstions above included editing
- OEM strings in the boot sector. Could someone please enlighten me what
- that does, how to do it and what possible benefits might be reaped from
- doing so ? Many thanks to all of you for your help and suggestions.
