Re: Installing to an Amiga HDF



Thanks for all the advice guys.  I managed to sort it out by creating
the RDB and the partitions with parted and then using the -o flag with
losetup to mount the partition with the correct offset as /dev/loop7.

Then it was just a matter of using mkfs.ext4 on the loopback device
then mounting that filesystem as /mnt and extracting m68k-base.tgz
into it, remembering the p option too! :)

However, upon running 'amiboot-5.6 -d -k vmlinuz-3.2.0-4-amiga
root=/dev/sda3 fb=false' from a boot without startup-sequence I get a
"compressed image is too large! Aborting." error so until i figure out
this issue I have no idea if the partitioning voodoo I carried out
actually worked yet.

Kind regards,
Nik
