Today's hard disks and 80 conductor cables don't use master and slave settings. Try the new standard.
In closing, remove the 2nd drive since less parts means less parts to suspect.
I reformatted 2 30G HD, set one as Master, the other as slave. I tried to install XP on them, but it says it's checking the system config and then does nothing. So I thought I'd install 98SE and then the upgrade to XP Home Edition, which I had before. I got 98 on and then decided to put a fresh XP Prof. on instead. It ran the setup and when I went to open it, nothing was there. Win 98 was, however, but there were 2 OS on the HD even tho XP wouldn't run. I reformatted again and tried to reinstall 98 and it won't reinstall. It gets to the system config part and then does nothing. I keep fdisking it and reformatting, but to no avail. Any suggestions? It's an EPIA mini motherboard, an external floppy, 2 IDE slots, 256 RAM, embedded CPU and that's it.
