I use those modules a lot, i would say that they are more reliable than cf cards, in the datasheets sometimes include the CHS info, or iirc there is a utility that helps you detect that info.

I'm currently using an 128MB DOM made by PQI in a 286 machine - datasheet is available here.
The module is connected to an ISA-IDE card and controlled by XTIDE Universal BIOS (AT) on a NIC socket.

Don't know if that works fine with your 386, though. Maybe you'll need the ide_386.bin file.
Current beta binaries can be obtained here: http://www.xtideuniversalbios.org/binaries/

If you prefer to keep the old IDE BIOS code in control, just make sure overall disk size isn't exceeded when you're entering fake
CHS geometry information. And also take care of the 1024 cylinder limit: http://www.informit.com/articles/article.aspx … 31238&seqNum=14

If you take care of that, I see no reason why you shouldn't be able to use up to 500MiB of your DOM's memory. 😀

Edit: I used XTIDE Universal BIOS (AT) v2.0.0ß3,
in a vintage 27128 EPROM on a DLink NIC (DL2518).

Edit: Here's a dump of my 16K EPROM chip,
for those of you who may encounter trouble:

Edit: Here's a dump of my 8K EPROM chip, too.

Right, there is. IDE-Diag, for example.

Edit: Pictures added.

Amazing, Thanks for the download, was looking everywhere in my files for that

You're welcome. :)
