Clock on my server runs very fast. It is about twice faster,=20
and I think it is not good for a server. I'm running 5.1R. =20
The problem did not occur under 4.4R, 4.7R, or 4.8R=20
on the same PC. I know FreeBSD doesn't read time=20
from CMOS Clock. Right after rebooting the machine,=20
date command shows me a correct time because of=20
xntpd in rc.conf. The PC has AMD 350 MHz IBM Aptiva. =20
I pasted information of Timercounter =1B$B!H=1B(Bi8254=1B$B!I=1B(B and =
=1B$B!H=1B(BTSC=1B$B!I=1B(B=20
from dmesg.today below.

I added each line below on my kernel and configured as someone=20
suggested me but it didn=1B$B!G=1B(Bt work.=20

Also, someone suggested me that I might modify clock.c file in=20
/usr/src/sys/i386/isa/ but I didn=1B$B!G=1B(Bt know how to modify it.

Does anyone have any idea or know where should I ask?
