Intel also made a 90MHz 486 on 30MHz bus, though I am pretty sure theirs was only used in laptops.

Select 2x jumper and it will run at 4x speed.

Anyone think it would still be possible to attain 133Mhz by using one of those upgrade chips? Those often came with jumpers of their own 😉 Like the Kingston Turbochip or the Evergreen

*insert long RAM talk here* So after getting this thread derailed by RAM talk, it's time I bring it back on topic. I've almost finished recapping my Shuttle AV61V40 motherboard, although I just got a Soyo SY-6BA+ motherboard courtesy of my mother(she's awesome - if ever I need old computer …

Whats up with this thread. There are unofficial drivers for 8800GT for win9x, can find out over at MSFN. I haven't tested them personally. Besides Ace is talking about slot 1, not much over a Geforce 4 will work on AGP 2x/4x so that is a limitation. As for Ace, If you get your hands on a Abit BE6-II …

I think I need some different 1200uF capacitors than what I have for my Shuttle AV61V40 because they're about triple the width of the original capacitors on the motherboard. Most of the capacitors I found were considerably bigger than the ones originally on the motherboard, so some had to be mounted …

The voodoo 3 is overkill for a P2. hell, even a pair of voodoo 2's can make a 333-p2 work for its money. Personally i'd go with the awe64 for the P2. And you ALWAYS max out the ram. (with a p2 dont go over 512mb) having a k6-2 system and a p2 system is just redundant. the 486 looks good. again i'd …

sebaz_ri, How were you able to flash your M919 with the uniflash.exe program you uploaded? When I run uniflash on my M919, the option to flash the BIOS is greyed-out. All I can do is backup the current BIOS.

If setting up using jumpers make sure there isn't a AGP Divider that might be setup in the wrong spec. Maybe its booting at he 1/3 setting instead of the 2/3 divider? Have you tried pulling the power, pull the battery then clear the RTC as well? This has helped me in the past with many things. Also …

This Pentium II computer is mainly meant as a test box so I can test various sound cards on all the MS-DOS games I have and get some clips from those sound cards for my "The Many Sounds of:" series of videos on YouTube, so AGP graphics cards are not a priority for me. Besides, the picture quality …

I've been there, I had a PII-400 tricked into 266mhz by setting the bus clock to 66mhz (cpu has locked multiplicator). but I found the design to be too unflexible, some games were running to slow, some games were running to fast, it just didn't feel right most of the time. I ended up in building a …

Would there be some way I can underclock the Pentium II to below 200MHz? From what I can tell, the Pentium II I have is multiplier unlocked, but the BIOS settings only lets the Pentium II underclock down to 200MHz. This is still too fast for me to test sound cards with the Collector's CD-ROM edition …

which mainboard do you use? does it support jumpering 2,0 multiplier in order to get 2 x 66 = 133mhz clock speed? EDIT: WTF??? I just installed MS-DOS v6.22 on my Pentium II computer and whenever I boot DOS, I get almost two lines full of garbage characters! And the computer has crashed. What the …

Yes! There is 3 jumper on Evergreen 5x86 133 (1 have them on my 2 vlb 486 computers ) On old 5v 386/486 vlb board and On a 486vlb 3.3v /5v i change it with a 3v 5x86 133/ 150 (3x50) i can't to have x4 (again :( ) for 133 or 160 ;) One is detected at 120, but it's only on boot (i can't to update bios …

Great... things have just gone downhill. I installed MS-DOS v7.10, but I can't boot it at all. To make matters worse, I can't even start up the setup program for MS-DOS v6.22 from the floppy drive anymore! WTF?! What the hell just happened?! EDIT: Seems like the hard drive might have something to do …

I'm wondering something. The "wire" bridging the jumper looks to be much sturdier than ordinary copper wire. It looks to be about as stiff as the wire a paper clip is made of. I wonder if you were to clip it precisely in the middle then bend the ends upward if you could slide a jumper over it so …

Okay guys, I need some help here. I just installed the DOS drivers for my SoundBlaster Live! model CT4830 but I'm having problems. The SoundBlaster 16 support works fine, but the FM Synthesis is abnormally slow and causes all DOS games to stutter pretty badly. What's causing this? General MIDI is …
