Didn't realise you had an EPROM programmer, that's useful.
It's the right chip and it's a Phoenix BIOS, the one I have is an Award BIOS. I've programmed a 27C1024 with yours and it will let me boot off the CF card using my modified XTIDE although it hangs for a few seconds on a warm restart.
I'll have to dismantle the machine to remove the XTIDE EPROM from the network card to try it standalone.
The XTIDE is probably overriding it. I wouldn't be surprised if without it the BIOS would automatically fallback to "no drive" if it doesn't detect a Connor on it's own IDE connector, but maybe his BIOS is old enough, as I think only the later revisions have this limitation. Can you try using his BIOS and attaching the CF adapter to the Toshiba's IDE? If it doesn't work, it would definitely be quicker and cheaper for Vipersan to flash a new BIOS than to opt for an XTIDE custom network card.

So the two patchwires modification is needed for the 5200 specifically in this case? Sorry I misunderstood, I thought the T3200SX would have a different pinout but apparently it has the standard 26-pin layout.
Would the modification you mentioned also work for me on the T3200SX?
Yes, I double-checked and the FDD pinout from the motherboard on the T3200SX and the T5200 are identical, so this modification would work. In fact, I believe the user on VCF tried it on a T3200SX and got it to work so I tried it on my T5200.
The reason I went this direction was to see if there was a solution that did not require creating a custom cable, which of course works just as well.
I also forgot to mention that I removed the molex connector from the adapter and soldered the wires in directly.
Thank you very much for the info. I will probably opt for an adapter in this case, I just have to find out whether there is enough space behind the FDD, as in the T3200SX the cable is very short due to the connector being quite close to the drive itself. But if you say that a fellow on VCF used it successfully in a T3200SX, then I have good hopes.

Don't forget that the IDE cable likely has one connector fitted backwards so you can't use the standard cable to plug into another IDE drive without checking that and if necessary removing the keyway bump.
If in doubt, use a standard IDE cable for testing.
Aye, if in doubt, check the original cable from the old Conner drive, IF you still have it. In my case (T3200SX) the cable had the connector's the correct way around. (@Vipersan)
