Apparently it claims it supports a upto a 1024KB cache module! I very much doubt they ever got released! Here's the spec from my manual

Here's mine. I think it's a M919 motherboard. Sorry I can't remove the stickers but hope the photos and the scan from the manual should give you some sort of clue. http://i185.photobucket.com/albums/x305/bradg1982/WP_20150324_21_56_45_Pro.jpg http://i185.photobucket.com/albums/x305/bradg1982/WP_ …
Re: AT boards in ATX cases

Another thing that could be an issue that the ATX case only has 7 expansion slots where the AT case has 8. Thankfully most AT motherboard does not have a expansion at the eighth slot. One of my systems does have one there. It just simply can't be used. Here's my two. http://i185.photobucket.com/ …
Re: Asus P5A wierd boot issue
Posted on 2015-03-14, 21:10
Yep my Asus P5A mainboard does the exact same thing. I don't know why either. Which is a bit of a bummer because I always turn of the mains at night via remote. When I turned the mains on the computer turns on right away. 😖

Replaced most of the capacitors. However the odd sound issues still exist. I didn't expect it the issue to be resolved anyway. So the HDD is still connected to the RAID controller and the CD-ROM to the Sound Blaster 16. Just noticing the two caps I replaced several years ago! What an amateur I was …

Found the sticker! Yep it's a V1.0 found right by the BIOS chip - Thanks for the information KT7AGuy. Also thanks to shamino for the capacitor information. I do have most values already to hand so will get to work on it soon and order the ones I don't have. It's worth a try at least. 😀

Interesting. I had no problems with a PCI sound card in mine. I had a good search trying to find what version I have but gave up. :-) I believe I have the V1.0 when I somehow managed to have found out when I bought it 11 years ago. I know it has the latest BIOS as far as I know. I have only replaced …
Re: AWE64 Gold CT4390 Midi plopping bass issue
Posted on 2015-03-06, 18:09
I've had some games where the midi sound went all bad, in my case it was because the MHz of the Pentium was too fast. at 200MHz there was bad hanging notes, at 166MHz the problem was still there, then around at the 150MHz and 133MHz area, all was well. My friends computer back in the time of 1996 …

Well made good progress I've ended up moving the HDD to the RAID Primary IDE port and installed the HPT370 driver with success under Win98SE. But still got the sound problem during CD-ROM access. Moving the CD drive to RAID port caused the drive not to be found but however the Sound Blaster happened …

All the capacitors on the Sound card are fine and works perfectly well in another ISA bus system. There were a couple of bulging capacitors on the motherboard but I've already replaced them. Change of topics here is my northbridge heatsink on mine. Looks like a Zalman universal one. It was already …

I've got the same ABIT KT7A-RAID that had a AWE64 Gold but had to removed after I started to experience problems with the sound which slurs really badly during HDD and CD-ROM access. It's fine otherwise. I had the same problem with the Sound Blaster 16 Pnp & ESS1868 Audiodrive. Disconnecting the IDE …

That's impressive! 😀 486's normally have turbo switches as well. Yeah I decided to have the switches at he back I didn't want to modify any of the front, I like it to keep it's original factory look and it can be changed back if I ever need too 😀

Old topic but problem solved. Bought brand new 3.6v Ni-Cd cell rechargeable batteries from Hong Kong. Time and date carries on fine now when the computer is off. Still decided to keep the new battery on wires and safely away from the mainboard so if that ever does a leak the board should still be …

Need help please I'm wondering if any of you know who made this card and where can I find the jumper pinout for it. The chip is a Winbond W83787IF 007AB192371602ND and the only reference on the printed circuit board is SIO-V2.1 It looks like it's been made around March 2000 according to the date …
Re: Having trouble changing CPU MHz speed
Posted on 2014-08-03, 21:22
I think I've found it. It's a square silver tin that looks like it's removable it's got a cable tie around it and it shows 25.000 MHz on it. So I assume to change the FSB of the board you will have to change that part. It's not worth investigating further, cheers for the info anyway 😀
