No, it needs to be an ext2 partition. AFAIK the first 1k of an HFS
partition isn't free.
The way that the older OF boots from a hard disk partition is that it
uses a couple of fields in the partition table entry which give the
location of the bootstrap in terms of the start and length of a
contiguous set of blocks in the partition. OF just loads those blocks
into memory and jumps to them. The quik installer program sets those
fields to point to the first 2 blocks of the partition.
So in principle it would be possible to put the quik first-stage
bootstrap on an HFS partition. You would just have it as a contiguous
HFS file somewhere and set the partition table entry to point to it.
Paul.
