Hi grml. My computer has a no-award bios which suffers from problems booting USB-HDD devices. As I can tell I'm limited to a single 1GB partition although iso images installed via dd do boot. Currently I have a usb device which boots kernel with an initramfs ( embedded ) that activates raid ( metadata=1.2 ) and lvm on mirrored sata drives that contain root partition. I would like to replace this initramfs that contains little sysadmin functionality with grml and see a few options of how to realize:

1-grml persistency, but I think my bios constrains will make it difficult to do iso leaving ~300MB enough for home-rw, live-rw, and GRMLCFG ?

2-customizing an existing grml iso image to include a default grub entry that mounts root=/dev/md0 with a fallback to grml ?

Other ways or suggestions ?
