Hej
Måske er den slet ikke slettet, - se følgende: (Fra anmeldelse af

Ptedit to the Rescue
If you are using Windows 95/98, and an
extended partition like my experiences above, then you may
need to change the extended partition type
from Microsoft's Extended-X to a normal extended partition
type. You will know in a hurry if you need to
do this, because OS/2 won't see the extended partition or
logical drives at all, period. Anyhow, if you
need to change partition types, you need the ptedit.exe
program that comes with the boot disks you
created from the Partition Magic 5 CD. If you want to access
the file directly, it lives on the CD under
the \dos-os2\disk1 directory.
Boot Partition Magic from floppies - you will
have to start Partition Magic from floppy disk 2 since the
install forces you to insert disk 2. Then
exit the Partition Magic program which will give you a DOS
prompt (a:->). Take out disk 2, insert disk
1, and type ptedit. That will load the neat partition table editor.
When the table editor comes up, look for the
first extended partition (the wrapper) that comes before any
logical drives that you have created. It will
have a table entry of 0F. Highlight the entry and replace it
with 05. That's it. Save and exit the
partition table editor.
Now OS/2 and Windows 95/98 will be able to
share logical fat partitions, as long as you don't exceed the
dreaded 1024 cylinder limit we talked about
above. And remember, just in case something goes wrong
you can always rerun the partition table
editor and change the entry back to what it was before (thought
you'd want to know). As with Partition Magic
4, there's no real detailed readme or document explaining
any of this, but the fix is real, and it
works.
For those who are totally confused by now,
remember that all these limits seem to only arise (at least in
newer machines with BIOS later than mid-90's)
with drives over 8.4 GB. That's because your system
BIOS uses INT13 to 'trick' your computer into
thinking that there are less than 1024 cylinders, 256 heads,
and 63 sectors. To oversimplify, your
computer does this by using in effect a translation table via
extended INT13 functions. However at some
point, either your system BIOS or your operating system
decides that you've exceeded the 1024
cylinder limit and that's all for DOS, folks. I haven't had time to
mess around between (Normal, LBA & other)
choices in the system BIOS to see if it makes any
difference as to whether & when you hit the
1024 cylinder limit, but would welcome feedback from those
who have tried. At a pure guess, I suspect
some interaction between the system BIOS and your hard disk
firmware.
