Re: [TCLUG:16545] Partition sizes?

[Eric F Crist <ecrist@ardent-hacker.net>]

Just a note.  I have a 13GB HDD with two partitions:

1) hda1: 12 GB (root)
2) hda2:   1 GB (swap)

and

3) hdb1  10 GB (FAT)

I don't remember what the exact values are, but I do KNOW that my root partion
is greater that the first 1023 cylinders.  Never had a problem.  Maybe it's the
version of lilo I run?
