Hi,
Have a major problem! Have an old IBM-AT and a Wyse 286 (4
years old). Both machnies have or had 1.2M 5.25" A: drives and
720K 3.5" B: drives. Both B: drives need to be replaced and
upgraded to 3.5" drives with 1.44M. After several attempts to
install it became clear the BIOS or something was not going to
let the machines understand a 1.44M drive was present. The
directory on both harddisks could be read but gets "sector not
found" errors when data is being read from the disk.
Do I need to buy a new BIOS??? The floppy 1.44M drives are
Mitsumi 45223. We have tried using a newer controller cards in
both machines (DTK 2-FDO card), with and without the card's BIOS.
HELP!!!!!!
Thanks for any suggestions.
Earl

I am currently having exactly the same problem with an old AT. There may
be several of us, so maybe replies to the net would not be out of order.
Thanks. --gary

You are right, the bios doesn't know about 1.44 meg drives because it's to old of a bios. Now, don't go crazy, there are solutions. <grin> What I'm currently using is a program (actually a suite of programs) and a driver from a company called Bastech Inc. out of North Hollywood, CA 91605. The software is dated 1988 and I got it from a friend (original disk). What you have is a device driver that you load in your config.sys and some utility programs that will let you read/write/format 1.44 and 720 3.5" drives. I don't know how easy to come by this software is but it works for me. It is not the best solution however. The second solution that I know of is to purchase a newer hard disk / floppy controller card that has it's own rom bios built in. This will function better than the software driver and it will allow programs such as Norton to recognize the fact that you do have a 1.44 meg drive around for use. When I use Norton for formatting disks, the software solution doesn't provide Norton Utils with the information on the drive so Norton doesn't know it's there. You have to use thier format35 software for formatting disks. The hardware solution I believe works just as a normal drive would work. I don't really know for sure as I don't own a newer RLL controller with the Rom built in. I have the old original MFM card that was supplied with circa 1985 IBM AT machines.

I has a 5.25" drive only but I temporarily installed a 3.5" drive when setting up a network. i know it might sound obvious, but did you try changing the setup ?? I know it worked for me ! I was able to set up drive B as a 3.5" and I know that I could also set up another 5.25" with extreme ease... Try changing the set-ups, it should work.
