Here's a strange one that's currently on an auction site. "Nexar ISP4106 AT PC Pentium". Stickers suggest it's from July 1996. FCCID is from March 1996. At first glance it looks like your standard clone case, but it has a side access panel that let's you can reach the RAM, Cache & CPU without …

Nice score! However the DX2-80 and DX4-120 are definitely not low bus speed for 486 class, as they are 40 MHz bus, rather than the typical 33 ... You are right. They are the faster bus speed. I completely spaced that. Thanks for pointing that out. I'd guess that the difference between the 33mhz …

Holy crap what a score! Are all the socket 4 Pentiums 60 Mhz ones? You got a lot of pin unbending to do or were they stacked in carefully? There wasn't really a green/brown cutoff, you can get early palomino XP on brown, slightly later pally on green, then early Tbred A seemed mostly brown, then …

JMicron ones (or at least some chip models) have issues with VIA 686B and Intel ICH4 based IDE ports. (there may be others) Oherwise, they work well. I've had trouble using the Jmicron bridges with the Promise PDC-20630 based VLB controllers, which was disappointing because it's been the fastest …

I checked the raw disk image and it produces the same warnings, so I'm glad it's not something I "added" to my backup back in 03. Certainly the most interesting VLB driver that I've seen so far! After getting the explanation about how it works, it seems to be more of a copy protection scheme than a …

But soldered, no socket. Would the 170MHz RAMDAC give some additional modes? Anyway I am not going to desolder the existing RAMDAC, so upgrading is not an option. Can you post a picture of your board? If there's a socket for a new ramdac, there's probably a way to disable the one soldiered on your …

For i815, I'd say Intel Desktop Board :). Totally non-overclockable but usually high quality Japanese caps and decent build quality. Some of them came with integrated Creative sound chips. For slot-1, I'd say Asus is trouble-free in most cases. Abit had BH-6 that was not affected by capacitor …

Don't really think it needs driver. It's probably just to add some additional/proprietary functionality, since the card is jumper-based. It might have the 32-bit Win3.x drivers on the disks, though. Turns out that the driver has some effect on performance. I got the best throughput performance out …

I would recommend using a socket 370 intel 815 board. I agree, the socket 370 & intel 815 board is probably the way to go. It's the sweet spot for AGP at x4 with a 133mz fsb processor. I have a 440 BX system. It's nice & compatible and I needed 3.3v AGP . Curiously, it works with up to 768MB MB of …
