Description of problem:
I have an aged 486-based computer that's been running RHL 4.2 for years.
The computer contains a pair of Quantum LPS 420A drives with
According to fdisk on RHL 7.1,hda has these partitions:
1   1     20     8134+  82  Linux Swap
2  21 1010 403920    83  Linux
hdb has
1   1   20   412054+ 83 Linux Swap

the installer complains about hda. Before I've even chosen which drive to
install to - for all it knows I might want to install to hdb.

The existing partition structure has been on hda since RHL 4.2 was new.

How reproducible:

Steps to Reproduce:
1.Partition your drive as above
2.Try to install RHL 7.1

Actual Results:  "An error occurred reading the partition table for the
block device hda. The error was:

"Partition(s) do not end on cylinder boundary."

It goes on to explain that this is because the drive geometry detected by
the kernel is different from the drive geometry used to partitiion the

Expected Results:  I expect to be able to install to this drive; if not
that one, then at least to the other.

It happens I'm happy to repartition the drive.

Additional info:

I've classified its severity as "High" because as it stands it's unusable.

Try passing 'linux noprobe' at the syslinux bootup screen.  This *should* allow
the kernel to be more liberal in it's interpretation of disk geometry.  Does
this solve the problem?
