i have an Asus A7A266 Socket A MB (ALiMaGiK 1 chipset, 1.25 GB DDR RAM) with
an AMD Athlon 1.4 GHz chip, running Windows XP. according to the motherboard
monitor utility, even when XP is idle the CPU temperature is running between
60 and 70 degrees C. this seems too hot, especially as the chip's max is
supposed to be 90 degrees. recently on a couple of occasions while running
an emulator the chip has overheated and the MB has sounded the overheating
warning. i replaced the CPU heatsink and fan but it didnt improve the idle
temperature. i've noticed that sometimes (intermittently) the PSU fan doesnt
start spinning at all when powering on the PC.

1) does it sound like the PSU is the cause of the problem in this case? or
is there something else i should be checking first?

2) what do i need to look for when searching for a compatible PSU? i know
there are different wattages, voltages etc available but how do i find one
that will work with my system?

any help appreciated. thanks!

Hello,

Since a few days I have a second-hand motherboard (Asus A7V400-MX) with
a default memory dimm of 256MB (DDR PC2700 256MB). Because I want to run
SuSE Linux 10.3 on it to manage my synthesizers, I had to extend the
memory with a dimm of at least 1 GB. My vendor gave me Kingston
KVR400X64C3A, which I had installed at once. After booting up, the
computer signal a long beep, what means that the memory was not
installed or detected. Is it possible that the memory does not suite the
main board? The manual of the A7V400-MX mentioned the memory module as
applyable, so what could be possibly went wrong?

Kind regards,

Johan.

I tried to find a copy of the original specifications document for the
IBM PC XT/AT, but I wasn't able to. I wanted to know what was the
memory map of the original IBM PC XT.

I remember reading that the regions from 0xA000:0 till 0xFFFF:7FFF
were reserved for something other than memory mapped IO.

Did the concept of memory mapped IO exist in the PC XT at all?

Thanks,

Gentlemen,

We are looking for two IBM documents that are needed urgently for a
project. They are titled "4680 Store Systems Serial I/O Channel Attachment
Information" and "Serial I/O Product Attachment Information". $100 will be
paid to the first person to deliver either or both of these documents in
their entirety. If you have partial documents or you are not sure please
contact US anyway. The contact person is ty@rocketfarm.com

Thank You,
Bob

Can someone recommend a rackmount single-board-computer case that takes
hotswap hard drives? We are stuck using Altigen for a phone mail system,
and it unfortunately uses PCI cards for its extensions and trunks. The
case we currently have has terrible hard drive access, and I need to be able
to quickly swap out hard drives when one fails.

I am hesitant to try to use modern Dell or HP server systems since those
have slots for PCI-X cards and I'm leery that antique PCI cards would work
well in such a system. (I welcome opinions about PCI compatibility in
modern servers.)

Well I'm not sure if this is the right forum to ask this question on but
here goes!

I have four IBM POS VFD Customer Displays aka "Pole Displays" This is
the one attached to various IBM electronic cash registers that shows the
customer the price of each item as it is rung up and then...

I'm familiar with cheap video cards that used system memory and took a
preformance hit as a trade-off.

When I look at a current mobo with on-board video, this one for
instance, does the video chip have it's own memory or do I have to
assume shared memory design?

I'm not looking for 3D or gamer performance, but if I buy a fast CPU
and want to make it work hard, I don't want to be slowed down by the
memory subsystem.
