Something is wrong there, any box that can run a PII450 will

I'm not sure about this one. All I know is it's a strange and uncommon
board. It didn't have a SECC retainer fitted and hadn't had one when I got
it. Just the slot. From what I remember it was only very early boards that
were like this. It's a VX chipset and, until I found the manual, wouldn't
have dreamed of trying a Deschutes CPU in it, I originally set it up with a
Klamath, then found the manual on-line so put the 450 in.

It may even support a Coppermine with the right slotket,
maybe even Tualatin same as typical BX chipset board would,
except that's probably beyond the capabilities of the
voltage regulator circuit, especially extended use at near
full load, like SETI/etc would cause.

ZX should support low-density 256MB modules, but stability
of *anything* on such a low-end, aged board, could be harder
to attain.

Ok, the problem. This machine runs Prime95 for 24 hours no problem.
It runs SETI CLI sweet *but*, I have the monitor set to turn off
after 10 minutes, no screen saver. If the machine has completed a
SETI WU and it's got the monitor turned off it locks up. No mouse
movement or pounding of keyboard will wake it. A hard re-set is
needed. This has happened three times and every time the first thing
the PC does when it starts is complete the last 10 seconds of a SETI
WU and then connect to get another one. It's connecting through my
LAN at the moment.

You might see if the NIC driver properties has different
settings for power management, and see if any bios settings
seem related and enable them... hard to say on an old
lower-end board like that.

I can't find anything relevant.


Maybe just leaving the monitor disconnected & off, then
never allowing OS to shut it off would suffice?


Some boards with power management wakeup problems, benefit
from bios update.

I can't find a BIOS update for it. It doesn't have a very large
web-presence.

I got the manual from he

www.elhvb.com/mboards/ a-trend/manuals/

Atrend 6310M

You might find that other PCChips et al boards' bios would
work, providing the I/O chip and chipset are same (or
perhaps one with BX chipset would work too, unsure about
this. I do think the board was designed to accomodate
either chip, hence the missing 3rd dimm slot when ZX is
used... don't recall the other limitations of ZX vs BX at
the moment.



You know, it's *almost* this board:

Linked from that page except mine has an Intel chipset, the third SDRAM slot
nearest the AGP slot is missing (but there is allowance for it) and the FDD
connection on mine is over by the serial/parallel connectors (which are also
oriented at 90° to the ones on that board.

At first glance I thought that was it.

Thanks for your input Dave.

I'm pretty much out of ideas, beyond looking at power
management and trying a different NIC and/or NIC driver.
I'd probably just turn off monitor manually and disable all
power management except HDD spin-down, if access to the
drive can be delayed long enough... if not then perhaps a
ramdrive for storage, any file I/O happening that would
otherwise keep HDD spinning. Then again I vaguely recall
that there's some sort of diskless client potential for
SETI, if you set up boxes like that it wouldn't need the
HDD, monitor, etc.
