NO WAY!

Hmmm. I played it safe and kept the filecore partition to 1998MB.

No, because the RISC OS partition starts at 00 (IIRC)

I get exactly that error with unixfs when trying to mount the /usr
partition (which is at over 2GB on my disc). I can, however use the
root partition with unixfs which starts at under 2GB (just).

Is *anyone* using unixfs with partitions starting at >2GB on an ide disc?

Doesn't sound good...

Only thing I can think of is to boot of floppy and use fsck -f on the hard
drive. I _think_ this will be possible but I'm fairly new to RiscBSD too...
