Not able to install so not possible to give.
>Description:
6.5GB ATA33 IBM HDD, on Biostar M7MIA mobo including the VIA IDE controller identified by the boot process as a "VIA 82C686 ATA66 Controller", althoguh it may be the 686B chip not the 686. Full spec included below.

Hard drive partitioned as 4.5GB Win2K/FAT32 partition, rest empty awaiting a FreeBSD install. I've checked out the hard drive with the IBM disk testing utility and all tests passed fine (I've even tried doing a "low" level format on it using the IBM wipe utility,
to no avail), also windows 2000 installed without problem.

I have been booting from 4.1-release install CD, set up kernel as usual knocking out all the unused hardware and sorting out any conflicts. Picked express setup, created a FreeBSD partition, sliced it as per my requirements (100MB root, 260MB swap, 300MB /var, and the rest for /usr), picked the minimal distribution (althoguh picking any of the others has the same/similar effect), install begins. This is all much as I've done before with no problems before the new motherboard & hard drive re-format.

At a seemingly random point while either extracting/installing the distribution, or while the "Remaking all devices.. Please Wait!" message is on screen shortly thereafter, the computer pauses for a fair time (probably around two to five minutes, not always the same though) then displays the messages...

panic: page fault syncing discs... 374 374 374 374 374 374 (repeat 374 a total of 20
times)
giving up on 328 buffers
Uptime: (whatever)
Automatic reboot in 15 seconds....

I've a strong suspicion this is related to the hard drive controller, althoguh I've not been able to find any problems reported anywhere around the net with it, so that assumption could be wrong.

Also, on one occasion while trying to install, it did manage to complete the install, and it rebooted successfully once, but after a few minutes of use I had a "read command timeout" error, followed by a seemingly endless loop of the OS reseting the drive controller then it failing again, reseting again, failing again, and so on, only solved by
a hard reset. On restarting FreeBSD wouldn't even boot, crashing out with a "BTX halted" error and a load of hex (which I'm afraid I didn't think to note down, there was a lot of it) and no error codes or messages aside from this.

HW Spec:
Biostar M7MIA motherboard, using AMD761 north bridge and VIA 686B south bridge
128MB DDR PC2100 memory (under-clocked at 100/200MHz to match FSB of processor)
AMD Duron 750MHz CPU
IBM Deskstar 6.5GB ATA33 Hard Disk Drive (partitioned as 4.5GB FAT32 Win2K, rest FreeBSD)
SMC 1211TX-WL 10/100 WOL NIC
ATI Radeon VE 32MB DDR Graphics
12x ARTEC DVDROM
3.5" floppy drive, 1.44MB (wow)



>How-To-Repeat:
Put in the install CD and attempt to install.
>Fix:
No idea, I'm afraid.
