I had the same problem with a compaq 286-10mghz, its rom bios did not support the 1.44 because it was (1.44) was made after the 'puter. I suppose it would depend on the individual machine and whether the bios could be upgraded. Other than that, the newer 286's should support it ,yes?

I am trying to install a 1.44 meg floppy in a IBM AT, however the setup doesn't support it, it only supports the 1.2 Meg floppy. Has anyone done this before? The machine has DOS 3.10 installed on it. Maybe it needs a special driver, and/or BIOS upgrade, and/or a DOOS upgrade. Any IDEAS? -- --------------------------------------------------------------------- David L.

You will AT LEAST need to upgrade to 3.2/3.3. There could be other problems too depending on the BIOS or controller you're using but you should try upgrading DOS first.

You'll need 3.20 for 720k (came with the Convertible, I think) and 3.30 to go 1.44MB (came with the PS/2's) Also, you'll need a BIOS that supports a 1.44MB floppy. Some people claim that just using DOS 3.30, and drivparm/driver.sys will do the trick, but this did *NOT* work in my old (c.-86) Sperry/IT AT-clone. I did, however get the drive (a TEAC 235) to go 1.44 using the public domain program fdread.exe loaded as a TSR to read/write, and the companion program FDformat.exe to format. If I tried to write to 720k floppies in this 1.44MB drive, they got thrashed. (General failiure...) I've heard about a 'Compaticard' floppy controller that comes with it's own BIOS, (and perhaps a device-driver???) that can get a 1.44 working on any type of PC. (about $90-100 in an ad in 'Circuit Cellar Ink') (The card even did 8" floppies :-)) -Terje ____________________________________________________________________________ thoger@solan.unit.no | Institute of Physical Chemistry THOGER AT NORUNIT.BITNET | Div. of Computer Assisted Instrumental Analysis | Norwegian Institute of Technology

So the price goes a bit beyond the $90 for the hardware ... add about $75 US I think for the software. It does work well .. I use mine quite a bit.

The CompatiCard includes the drivers necessary to support standard disk formats. Uniform-PC is only necessary if you want to accomodate hundreds of non-standard formats. Uniform-PC does not require a CompatiCard. -- Mike Berger Department of Statistics, University of Illinois AT&TNET 217-244-6067 Internet berger@atropa.stat.uiuc.edu
