[comp.os.msdos.misc] SMARTDRV/DOS 5.0 and UNIX partitions

pss1@kepler.unh.edu (Paul S Secinaro) (06/24/91)

I have a Gateway 386/33 with a Phoenix 80386 Bios Plus version 1.10 M8,
with, I believe, a Seagate/Imprimis ST4182A 150 meg full-height ESDI drive.
The disk has a UNIX partition on it, and the DOS 5.0 SMARTDRV won't install.
Here's what the README.TXT file says:

--------

7.5 SMARTDrive and Third-Party Partitions
-----------------------------------------
If your system includes a third-party disk partition and you
try to use SMARTDrive, you may receive a message stating that 
you cannot load SMARTDrive. 

You can force SMARTDrive to load by specifying the /p switch.
However, doing so may corrupt your hard disk if either of the
following conditions is true:
   * Your hard disk contains more than 1024 cylinders. 
   * Your hard disk is not supported by the system's ROM BIOS.

If you have partitions created by using third-party
disk-partitioning software, use SMARTDrive ONLY if you are sure 
your hard disk contains 1024 or fewer cylinders AND it is 
supported directly by the system's ROM BIOS.

----------

Can anyone elaborate on this problem?  Why does DOS 5.0 seem to have so much
trouble with partitions?  Can I SETVER an older version of SMARTDRV, and, if
so, will it still be dangerous?  (A few months ago, the DOS partition
on this drive WAS corrupted, but I'm not sure what caused it - it may have
been CHKDSK).  The SMARTDRV from DOS 4.01 seemed to work fine.
Thanks,
Paul Secinaro
