It doesnt matter if you have a MFM or an IDE controller installed, both will work in the 286.

As said, disable the controller BIOS and boot from Floppy. Then check with any IDE low-level tool if the drive is detected.
If not, XT-IDE will not help you as there is another problem.

Here are some tools to choose from

Well, yes and no. What I was trying tegrady to tell was that the old 286 BIOSes weren't IDE-aware per se.
They will treat IDE drives the same way as if they were old WD100x series controllers. In some rare circumstances, this may cause
weird compatibility issues, since CF cards, for example, are compliant to the newest PATA standards (but not necessarily 100% to anything pre-PATA2, even though they support 8-Bit mode).
Sorry, I'm not that good at explaining such things, I'm afraid, hah. :sweatdrop:
What I meant is better described at http://www.os2museum.com/wp/how-to-please-wdctrl/

I tried booting DOS 5.0 (the install disk) from floppy, but it did not give me the option to install DOS to a hard drive, just another floppy. When I was using the old controller, which only allowed a 117mb hard drive size, it did allow me to choose to install to hard disk.

What program should I be booting from floppy?

Also, once I have done that, which IDE low-level tool should I be using?

Thanks.

OK, now I am trying to go back to the non-Promise controller without the onboard bios and try using drive overlay software.

However, all the driver overlay software I have found seems to require a 386 and locks up my 286.

I did see ANYDRIVE, but I can't figure out how to use it....

Thanks.

No time to turn on my 286 at the moment..but the tools are
Anydrive
DrivePro

The 1st two here
http://ibm-pc.org/utilities/hdd/hdd.htm

Anydrive is small and you have to copy it onto you DOS-Bootdisk and start it from Floppy.
Use any hard disk with any BIOS.
Have you ever tried to install a new Harddisk
in your PC and found that the BIOS did not
support it? I was faced with that situation
lately. I got advice to buy a new BIOS or to
buy a special controller.


If you get one og them running you dont need the BIOS at all.

But I recommend them for testing purposes to see if your IDE-Hardware is OK. It should detect your harddrive with Model, capacity etc even if its not initalized by any BIOS.
