RHEL AS 4 U2 Slow

[Brenda Radford]

Installed RHEL AS 4 U2 on an 80 GB HD (non-production, educational box).
When I turn it on, it is slow doing all the things it does when it boots 
up.
After it is finished, I right-click on Open Terminal, and it takes 
forever for a
window to pop up. How do I find out why it is so slow?

I have 895 MB memory and a 1995.494 MHz CPU.

The only thing I did manually in the install was to partition the hard 
disk (from df):

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda5              1004024    162144    790876  18% /

I do have a second hard drive that ran RHEL AS 3, but it isn't mounted in
/etc/fstab; it was done manually above.

I do have 2 errors in the kernel log, but I don't know what they mean:

shpchp: acpi_shpchprm:\_SB_.PCI0 evaluate _BBN fail=0x5
shpchp: acpi_shpchprm:get_device PCI ROOT HID fail=0x5

Thanks in advance for any information.
