I'm also running the slow end on the bios memory setting. The wz beta
bios is supposed to deal with some memory timing questions. I have
downloaded wz but haven't flashed the bios yet. I am running uz, which
became w? (their www server is overloaded and can't see what they
called the uz when it was released). Abit is also up to KT7a and 686B.
I have both Maxtor's (30 GB and 40 GB - ATA100's) set to do only UDMA
33 using Maxtor's udmaupdt.exe program. That didn't help FreeBSD.
Windows 2000 didn't have any problems at the UDMA66 setting and just
slowed down a little bit at the UDMA33 setting. I have three other
systems based on the bx chipset that don't have problems doing UDMA33.
If I time my upworld script, I see user times of 18xx seconds and
1.5-1.8 hours wall clock. I figure the difference between doing an
update (cvsup of RELENG_4 to installworld) in 40 minutes wall-clock
and what I have now is disk transfer speed related. Setiathome runs at
~40% cpu in the background (niced to 19). Because it is only using
available cpu time, killing setiathome before I started the builds
didn't change the build time significantly.
I have a Promise ATA66 card that I am going to try but will have to
move one of the HD's and CDROM before the 80-pin cable will reach. The
main drive is all by itself on the ide1 controller.
