It's a Promise multi i/o card. Floppy drive works, hard drive doesn't.. I think I stupidly moved some jumpers at some point and mislaid the manual.

If anyone has one and knows how to fix this/has a manual, it would be greatly appreciated!

Found a text based info sheet for the chipset, Promise PDC20630. Check, or post pic of the back of the card, for FCC number or part number, like Matth79 mentioned. The 5249X V1.00 turned up nothing from what i saw.

Unfortunately, many card manufacturers used this Promise chip. Kentech, CVT-T, Goldstar etc. The specific manual is the way for an easy setup.

However, a close-up high-res photo of the two bottom jumper rows might help give an educated guess. (The available JP4 sets IDE speed, JP5 / JP6 is for COM ports...) From JP8 to JP14 it gets more interesting

Possible mistakes:

- you might have jumpered an incorrect IO CHANNEL READY (still most HDDs should be detected)
- too tight IDE speed (latency)
- disabled the port entirely
- moved the port address from 1F0 to ?

Try moving the two jumpers on JP4 down.

There's a glitch in the matrix.

Of course, as always, I'm open to correction...😉

It's working again, and I don't know why! Don't think I altered anything else, but I changed the jumpers to put it into 'slow' VL IDE mode and it worked. Then changed it back to fast - and it still worked! Floppy is working too, so the only thing I care about otherwise is the serial port for the mouse.
