partitioning problem

[Tim Veazey <tim@supplyedge.com>]

I'm installing debian on a PC platform (old Pentium 166).  During
installation, I partitioned four spaces.

Name....Flags...Part Type.......FS Type.........Size(MB)
-------------------------------------------------------
hda1....Boot....Primary.........Linux ext2......100
hda2............Primary.........Linux...........200
hda3............Primary.........Linux swap......64
hda4............Primary.........Linux...........1645

I want to mount / on hda1, /home on hda2, and /usr on hda4.  However,
during the installation step "Mount a Previously-Initialized Partition"
I can only mount root '/'.  For any other directory, it tells me "Mount
failed:  No such file or directory".

Now, if I just proceed past this, I can get the core OS installed ok,
but the only filesystem I have is root (reported by fs).  I also tried
adding some entries to /etc/fstab and rebooting, but that didn't work. 
Under /dev I see a LOT of hda devices (hda1, ..., hda13, etc).  How
should I proceed from here?  Thanks for your help.

Sincerely,
