Re: [SLUG] Adding Ultra ATA PCI card (ide2) to grub.conf

The problem is that if the on-board BIOS intercepts Int13h,
setting its first drive as BIOS disk 80h in front of the on-southbridge ATA,
then that disk provides the MBR.

Then there can be disk mapping issues between the BIOS and OS kernel.
On MS-DOS (incl. 95/98/ME), it must boot a primary partition on that disk.
On NT, it depends if you are using a standard or dynamic disk -
but it typically won't boot until you change the BOOT.INI mapping.
On Linux, you do the same, change the LILO or GRUB mapping.

I can help you if you give me the full disk maping in your system.
There is not a configuration I can't get to boot with Linux.

The dog I was chasing is: is the drive bootable, if so is the BIOS having trouble finding it? I have no idea how to tell if a bios can boot from an added controller, I assume the bios extension on the added controller card takes care of it. Is the drive bootable when on a mommy board controller? -- 73 (= Best Regards) de: Ron ka4inm@tampabay.rr.com 100% LINUX, since July, 1997 SENT Time and Date are UTC Visit my HAM Web SITE at: http://www.qsl.net/ka4inm
