In general it doesn't - it either uses devicemap, or it's own biosdisk module to generate a devicemap on the fly. But it (GRUB2) is very powerful, and extendible (and scriptable). > > Regards > > Michael > <snipped> Your laptop [*1] doesn't appear to have BIOS support for booting from the CF card. Having had the time to do a little Googling (about 10 minutes) there are three possible routes (maybe more). 1. Boot from GRUB installed on hdd, using kernel and initrd copied from CF card install. Known to work[*2] 2. Boot from GRUB installed on the hdd, using kernel and initrd on the CF card. Should be possible.[*3] 3. Boot from GRUB installed on the hdd, using plopkexec[*4] to boot the kernel and initrd on the CF card. 'Might'[*5] be possible. [*1]"Dell Latitude" X1 A.K.A. "Samsung Q30". I don't have access to this device, and haven't taken the time to check, so I'm guessing about the lack of BIOS support for booting from the CF card. These things can be less than obvious - Windoof can mark a CF card RO which can render it unbootable, some BIOS require USB legacy keyboard support enabled before being able to boot USB devices - some PCMIA buses use 16-bit drivers which would possibly require GRUB to use Linux16. Have you checked for BIOS updates?
