Re: system clock is too slow

Thank you very much for the help! Below I am trying to provide the information...

My FC2's system clock is very slow, every hour it loses more than 30 min when the system is running, is there a way to find out the reason and correct it? Thanks.

What sort of motherboard do you have? What sort of hard drives and CDs,
and how are they connected?

It is a hp pavilion ze4400 (or compaq presario 2100) with Mobile Intel(R) Celeron(R) CPU 2.20GHz, inner QSI CD-RW/DVD-ROM SBW-241, inner ATA DISK drive 5400 40G

Does it make any difference how busy the system is? What happens if you
leave it doing nothing for an hour? (Try running init 1 to really shut
down background processes).

After init 1, I found my system clock only passed 31 min for an hour.

Can you do a couple of "cat /proc/interrupts"es on a really quiet
system, say five minutes apart?

results of "cat /proc/interrupts" are in the bottom.

Can you get hold of a DOS boot disk? Does the same thing happen in DOS?
(Try www.freedos.org if necessary).

There were no problem before I change from RH9 to FC2. The FC2 is a fresh installation. I may try the freedos later. Thanks.
