>Environment:
Windows 9X Extended DOS partitions for large disks (sysid 15)
>Description:
The machine dependent disk slice manager does not recognize
DOS partition type 15 (Extended DOS, LBA) as a container for
DOS logical volumes, so the appropriate slices (e.g. sd1s5)
are not initialized.
Note: This is a duplicate of bin/4120.
>How-To-Repeat:
Try anything that accesses a logical volume in the ExtendedX
partition. For example,
dd if=/dev/sd1s5 of=/dev/null
>Fix:
Look for sysid 15 as well as sysid 5 when looking for extended DOS
partitions in diskslice_machdep.c.
