Problems with Partion IDs

Is there a way to get Fatfsys or Dosfsys on either QNX 4 or 6 to ignore the
partion type numbers and try to find a FAT table?

For some reason my Win2k/Partition magic has made my FAT 32 partion have an
partition id of 28, thus it won’t use it…

Ideas?

Thanks
Kevin

For both Dosfys and Fatfsys (under QNX4), you can over-ride the scan by
explicitly assigning DOS drives to QNX raw devices.

Fatfsys a=/dev/fd0 c=/dev/hd0t28 &

Under Neutrino, I’d try something like:

mount -t dos /dev/hd0t28 /dos/c

As dagibbs said, you can give an explicit mount path to (QNX4) Fatfsys,
but you
can do it in a more generic (with regards to other DOS devices) way,
via:
Fatfsys c=/dev/hd0t28 -s &
This installs your partition and then re-enables auto-device-scan to
pick up
any other partitions or floppy devices you may have.

Those partition/boot utilities “hide” DOS filesystems by adding 0x10 to
the ID;
it’s really a t12 (INT13X-FAT32) partition.
