Do you know about the options you can get for the card and what should be selected?
There are a fair number of DIP switch settings as I recall. I know in my case that the XT-CF conflicted with the address of my ethernet card, and I ended up changing the ethernet card address. And from there I didn't change any settings on the XT-CF card.

I think these are all about the same, you can choose address, whether or not to enable/disable the EEPROM (rumor has it that you could put the EEPROM on an ethernet card and boot that way), etc. Here is one card with settings: http://www.malinov.com/Home/sergeys-projects/xt-cf-lite

Not sure if you are still working on this but I have a Compaq and disconnected the hard drive(it works) and inserted: CF Emulator and using as a hard drive. Works perfectly and extends the life of the hard drive and it uses Compaq setup disks which are 3.31, which I do have.

I'll have to see if it even has an IDE header, my drive is MFM I do believe.

While in there, before I take this whole thing apart... where's the CMOS battery located so I can check that. Anyone have any manuals, or diagrams for this beast they are willing to share?

Happen to be able to help me with DOS etc when I get all the parts?

After disassembly:

I only see a coin battery on one of the expansion cards, so now id scouring the internet to confirm where the CMOS battery is?
So, in my research I am not sure it has one, though Im confused because usually you have to enter the HDD params into SOMETHING and it must be saving it, as I never had to enter the info every boot.

Mystery Solved, me thinks it has no CMOS battery... I looked up the controller card for the HDD, and looks like its controlled by jumpers...


I guess i can put this baby back together.
