i have a future domain tmc-840 scsi card ive been kicking around for a few years, and i have just bought a external hard drive enclosure that has a quantum 210s drive in it. i want to put it on my Compaq portable or my pc xt but have no idea how to do any thing that's not plug and play :p. also there is a good chance this drive is mac formatted will i have to do anything to fix that?

Have a read here first:

Does the card have a BIOS? Other than the obvious Eprom sitting on the card you can plug it in and see if it shows up on the screen during boot.
Without a BIOS you cannot hard boot from the drive.

You will need to high-level format the disk drive anyway - previous format doesn't matter. But, if the external enclosure is from a Mac with a 25-pin connector *don't* plug it in to the card until you have sorted out the electrical compatibility.

Got any drivers with the card?

oh no bios which might be a good thing since i don't want to boot from the drive
still want to boot to the original drives as this drive is external

So all you'll need is a driver and a format utility. The biggest pitfalls are the on the hardware side. Safest to use the internal 50-pin ribbon cable to the disk, taking care to get the pin 1's matched. A terminator required at each end of course.

If you use the 25-pin external connection do your research before plugging anything in. There was a well-know conflict between Apple and Future Domain's use of the DB25 which resulted in a short circuit, if I recall correctly.

i guess ill have to use the internal connector as mine uses future domains own pinout on the outside port

The best driver for use with future domain tmc 8xx without bios is powerscsi 4.1 drivers from adaptec.

I use it with my fd850mex and I have hdsupport and external cdrom support.

The only problem is that this drivers use near 100kb of ram, and take about 2 minutes in booting all the drivers.

Is a short prize for have cdrom and hd in a xt...........iu know???


Try it and tell us the results, if you can make photos better.
