VA-503+ won't recognize D-Link network card - What's been your luck in getting the D-Link DWL-G510 wireless PCI netwoerk card to work in an FIC VA-503+ and Windows? I couldn't get Windows to recognize the card, no matter how I installed or the driver software, what PCI slot I used (other..

VIA C3 processor on FIC KA31 motherboard ??? - Has anyone tried the VIA C3 processor (on a slocket) on a KA31 I think I know where I can get my hands on an 800MHz processor for a price and wonder if it's worth trying. Maybe the BIOS doesn't support the processor - I don't..

hmmm... - I have a va503+ with a sb live card and a g-force 4 card. it's clocking 500 MHz with 384 Mb of ram running windows 2000. when I play a song with Windows media player, it plays great. but when I have the graphics turned on, such as the swirly ambient..

PCI problem on a VA503+ - Hi there, I've got a VA503+ , flashed with the modified APM bios (I can't remember the version - you all know what one it is), with a K6-2 500 (5x100), 256meg PC-100 and WinXP Pro SP1 installed with the F6(?) 'Standard PC' option. I have the lastest VIA.

The "highest" videos crads VA503+'s can use? - Hi there (again), So, after all these years, have the video card limits for a VA503+ been worked out? I was told once that cards over 32meg of vRAM won't work, but it that true? What are the highest nVidia and ATi cards that can be used in Windows XP?..

Well, this is the third part in a three part story. The second 503+
went to my mother-in-law, she's really happy with it. Her former
computer was a P 1 100 MHz, socket 5. nuf said. This is the last 503+ I
have, the reset doesnt work, and the sticker says 2900 I believe. ver
1.1, no ATX connector. Anyway, I flashed it with a newer BIOS, and then
found Cyrix M II 300 75 fsb in a box of free stuff from a donation here
in town. Never used a Cyrix before, I popped it in there, found the last
socket 7 heatsink I had, set the jumpers, no boot. Figured the 70ns 72
pin ram couldn't handle the 75 MHz fsb, popped a stick of 32 MB PC100
in, set the jumpers again, and finally got a screen . woo hoo ! Got the
manual out, and then noticed I had left the voltage at 2.1 that I used
for the previous K6 III+, and realized that was way too low. yep, top of
Cyrix says 2.9, set that and all runs well. Enabled linear burst in
BIOS, and I am off to the races. My question is, how well or how bad
does this cpu perform ? No gaming here, just plain old fashioned
computing. What would a MII 300 compare to ? P 133 ? ha ha. JK.

Cheers, John

The 300-ish rating is actually fairly accurate, as long as you are
talking about non-floating point calculations. My old roommate used to
have one back in the day. He actually would play games on it, using a
Voodoo Banshee 16 MB PCI card. For the time it was acceptable, but this
isn't 1998 anymore. :p

By the way, you can try running the CPU at (3.5x66)=233 instead of
(3x75)=225 if you want to use that EDO RAM and save the PC100 for
something else.

I have a MII300 somewhere (need a spare?) that I used for a brief
spell. It ran just fine for everyday business type applications. I
sort of recall overclocking it a bit to the 350 rating speed w/o
problem.

Speaking of fried, I had a HS fan fail on an old k6-233 CPU based
system and when I touched the HS to check the temperature, it burned 3
stripes on my finger, yet the CPU did not suffer any damage.
Replacement of the fan returned the system to normal operation much to
my amazement.

Alex, thanks for confirming that, these are two older 2 and 4 GB
drives, on the same cable. I may copy the primary to the better drive,
and ditch the smaller primary, then load a better busmaster driver. Back
in the day there were drivers made by highpoint, that could be used with
the 503+. I may hunt them up and try them. Like I said a while back,
this is all experimental and just for fun. I guess I am just trying to
prove that older computers run plenty fast enough for average pc use. I
just think that newer software is too bloated, is mainly multimedia
oriented, and if one doesn't edit video, play newer games, run
statistical programs, then a good P II or K6 2 is plenty. The Cyrix runs
pretty well for business use like Kyle said. The fact that we now have
to run anti-virus software, spyware detection software, and firewalls
unlike we did back in 1998 take up even more resources from the cpu and
computer overall. Why can't they make a smaller version of XP that won't
hog resources ? seems like I read about a version to be released in
Japan that is made for light duty computers. Myself, I have a lot more
respect for someone who uses a somewhat less powerful machine properly
than one who goes to Best Buy and buys the top of the line OEM part just
to send e mail. Oops, sorry for the rant, but that is where this is all
coming from. Yes I do run much more capable machines than these, but
this is a whole lot more fun in some respect. Plus it costs me little to
nothing. Thanks again !
