Some PCI cards may be a bit erratic with some of these boards, but if you have tried several different cards and none are detected, then there definitely is an issue. Have you confirmed all the CPU and bus related jumpers on the MB, so that you are not for example running PCI bus at 40MHz which could cause issues?

For IDE and depending on your HDD size, make sure that you have LBA set, if you are using some larger drives. Even with LBA set there are different limitations depending on the MB and BIOS and I think usually these boards max at 8GB or so, but it can be significantly less and they may have BIOS bugs that cause further problems.

So if your drive is something like 2+GB and even if you have LBA enabled, buggy BIOS or HDD size limit may be causing issues.

There is of course the possibility that there is a problem with the chipset itself as you seem to have many seemingly unrelated problems from floppy controller to IDE and to PCI, but check the above at least.

Nevermind about PCI. I put jumper and all works now. Tried 200 mb hdd, still bios detects, fdisk no.

SiS85C496 is one of those chips sharing pins between IDE and PCI, but since you managed to get PCI working its not the problem.
How about formatting \s HDD in another computer and checking if it will boot swapped to this one? You can always download MHDD https://hddguru.com/software/2005.10.02-MHDD/ and see if it can talk to HDD fine.

I have the same board and had a number of issues with some hard drives. The symptoms were similar to yours, where fdisk would not see the drive. Other hard drives worked just ok and I never managed to figure out why.
Try different cables, some drives just don't like 80 wire ones. Also, the autodetect feature can be a bit weird. It gives different options and the correct one is not always obvious.

Problem solved. Changed cable. Thanks.
