yeah, if it's not, no big deal. I only wanted this as a pure 386 anyway and it would save me an hour of desoldering the empty holes and soldering in a new connector. If I want a super speed 386/486 with VLB, I have an Alaris Cougar for that. H3nrik V! wrote on Yesterday, 06:52: Wikipedia says that …

Is it this board ? http://www.win3x.org/uh19/motherboard/show/2134 Because the unpopulated slot isn't a VLB slot from what I've been reading. Now maybe I'm wrong, but at least check that the voltages match a vlb slot ^^ That's the one. It seems to be VLB. 112 pins, MCA footprint, silkscreen says " …

I recently came into a 386/486 hybrid that has a footprint for a VLB slot that isn't populated. I'm planning to install a slot for it (I have a few), and I'm debating on what to install in this new fast slot on what I plan to be a 386DX 40mhz machine. Option 1: QD6500a VLB controller card. The …

On my STB Voodoo2 that doesn't work, C571 is a ceramic bypass capacitor, and has an in-circuit value of 1uf, which means it's probably closer to 0.1uf.

Hey all, I got a 12MB Voodoo 2 card a little while ago, and recently tried to use it, and it's not working. Like, at all. Causes the computer to totally lock up when a 3D application is launched.

What do you mean it is not detected on boot? SB 2.0 utility may not detect it if it is run on 486 or faster machine. Labs, I have this card installed on my Alaris Cougar build (IBM 486BL CPU) which is basically just a fast 386, and it sometimes doesn't detect unless I disable cache or change the …

Get a bunch of bulk extra-large ESD bags and an Impulse Sealer and some silica gel packets. The sealer will cost like $20-$25 I recommend a 16" one. Next, remove any and all batteries and make sure no capacitors are leaking/bulging. If you see one, fix it before storage. Then you'll want to use the …

One way is to fill up the unused space on the drive with dummy files. just make 40x500+mb CD ISO files and put them on the drive to take up space. I've had that work before.

The absolute best processor you can get in there would be an AMD P75 Overdrive. I recently bought one from ebay and it works very well on my Alaris Cougar. I would add a small fan to it, though. It does tend to get a little spicy...
