Sorry for the delay in replying. I've been trying various incantations, then the other machines psu fan stopped (ran out of oil) and tripped the psu's thermal cutout, so I had to spend a bit of time fixing that. Anyway back to the job in hand. I'v actually just got FC1 to boot from the main bootloader in hda, but that is from a kernel entry, not the chainloader. All I get from trying to chainload is a grub prompt. Running /sbin/grub I tried different drives to see if grub> root (hdx,0) would find somewhere to put FC1's bootloader. grub> root (hd2,0) printed the following, after also running grub> setup (hd2). grub> root (hd2,0) Filesystem type is ext2fs, partition type 0x83 grub> setup (hd2) Checking if "/boot/grub/stage1" exists... yes Checking if "/boot/grub/stage2" exists... yes Checking if "/boot/grub/e2fs_stage1_5" exists... yes Running "embed /boot/grub/e2fs_stage1_5 (hd2)"... 15 sectors are embedded. succeeded Running "install /boot/grub/stage1 (hd2) (hd2)1+15 p (hd2,0)/boot/grub/stage2 /boot/grub/grub.conf"... succeeded Done. There's some weird stuff going on here, as (hd2) hdc, is the cdwriter, and when I ran grub> setup (hd2) the writers light was flickering quite a bit, but as you can see from the output above, the bootloader installed ok. Another thing that is a bit weird, is that the kernel entries in grub.conf, apart from the latest from fedora legacy show a strange entry after label=/. Again, as below. LABEL=/ hdc=ide-scsi (perhaps this has something to do with Win ME identifying the IDE PCI adaptor card as a scsi controller) I've never seen that before. Quite what the situation is with the cdwriter now, I don't know. It wasn't showing up in the mobo's BIOS before. Only the cdrom drive (hdd), and the dvdrom (hdg) which I couldn't boot a distro from were there. As I can boot an FC1 kernel from the main bootloader, the harddrive on the IDE PCI adaptor card is obviously accessable, but there is obviously some problem with the BIOS regarding drive ID's. Webmin on FC1 still shows the harddrive on the IDE PCI adaptor card as IDE device E, and yet the mobo's BIOS is identifying this same harddrive as hdc. Anyway, the only problem left now is accessing the Grub menu. I've been back into FC1, and changed the splashimage from (hd4,0) to (hd2,0), but still only get the Grub prompt when trying to chainload to (hd2,0) hdc1, aka hde1.
