Well, I could think it's fate, but Bug'95 > recognises CD-ROM in the same condition! How can W95 find the CDROM if the BIOS can't find the harddisk to boot from in the first place? I suspect you have a port or IRQ issue here. Where is this 'second IDE controller'? It it perhaps on a Soundblaster card? In this case, it's actually the _third_ IDE controller, and you will have to change the port address of wdc1 using userconfig to the correct value. > Maybe kernel relates on BIOS too much?
