Hi Nigel,

Interesting - I've always understood that booting from extended partitions
was not possible -
of course that might only be true in the microsoft world. Maybe Linux boot
loaders are smarter.

Not bootable?

Funny, this system works for me:

Disk /dev/hda: 255 heads, 63 sectors, 3648 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1             1       510   4096543+   7  HPFS/NTFS
/dev/hda2           511      3648  25205985    f  Win95 Ext'd (LBA)
/dev/hda5   *       511       513     24066   83  Linux
