The messages are similar if I put it on the first controler, only
the second drive is wd1, not wd2. In either case at boot time it
comes up with wd(1,a)/kernel, boots, but can't mount root when on
wdc1. The motherboard is an ASUS PCI 486, and the CPU is an AMD
The root is assumed to be on the first controller in the file:
Perhaps your BIOS is (incorrectly) leaving 0x80 instead of 0x81 in the
Have you tried booting -c and changing the boot device at the config
prompt so that it will modify the kernel image for subsequent attempts?
This is different than booting the floppy and specifying the device
as other than the floppy at the boot prompt.
If the floppy kernel and the one on the disk do not match, you will
It should be possible to boot from the second controler on the newer
motherboards, and it can't be too unusual.
Booting requires that the BIOS drive number be correctly passed.
The motherboard BIOS is only going to know about 0x00 (A:), 0x01 (B:),
0x80 (C:), and 0x81 (D:).
You can not boot from a drive other than that.
Since the problem is that you can't mount root, I suspect you have
one of those bogus BIOS that doesn't correctly set the unit number
in the d register.
