I only remember it had a guy's name in credits and all it could do was enable clock doubling. I found it online sometime in 2001-2004 and used it with a cyrix 486slc2 upgrade. That's about it though, I remember nothing more... :( I know you say it is solely for clock doubling, but it looks like …

I take zero credit for the discovery, as I was pointed to one of epictronics' Youtube videos when I was trying to hotrod my PS/1. My original plans were pretty tame: ODP 486DX2-75, max out the RAM. However, a member who is on here and on another forum I'm on (rmay) shared the epictronics adventure, …

That may be due to the same bug that myself and epictronics experienced when we installed ODP 486DX4-100's in ours, which is fixed with the "TOM" BIOS. Hey, your mention of the TOM BIOS has me seriously intrigued—I’ve got to hear more about this. What was the deal with that ODP 486DX4-100 bug you …

My two cents… I have an IBM PC330 DX2 that i think share the same motherboard. After some test i found that the maximum you can install is a 4GB CF… but not all. I have 10 Sandisk 4GB differrnt series but all marked at 4GB. Probably some models are lettle less than 4096kb and work with no problem… …

Save your time and money. Use an Intel overdrive 486dx4-100 or Intel Pentium overdrive 83mhz. That would be ideal, but I haven’t managed to find one at a reasonable price yet, so I’m currently using an Intel Pentium Overdrive 63MHz. It’s capable of running at 83MHz, but it’s not very stable— …

I tried one of those 5x86 CPU adapters in my IBM PS/1. It worked but from what I remember the CPU cache gets disables or something like that. But it does work You need to set your motherboard CPU jumpers for 33mhz CPU. This IBM mainboard allows me to configure the FSB to 25MHz, 33MHz, 40MHz, or …

It does seem odd, doesn’t it? I can picture a bunch of frustrated customers back in the late ‘90s, stuck with systems they couldn’t upgrade to bigger drives. I recall around 1997 or so, I helped upgrade about two dozen Compaqs using ez-drive and a Norton Ghost image to make the process smoother. I …

Hey everyone, I’ve been tinkering with my IBM ValuePoint 466DX2/SP (6472-L5G), a 486DX2/66 I picked up recently. My goal was to breathe new life into it with some upgrades and get it running like it’s 1993 again—maybe even better. I’ve hit some snags along the way, so I’d love to share my progress …

Just to confirm , the bioses of these valuepoint series are very weird when it comes to hdds. I have a 466dx2/tp and it took many tries to find a hard disk that would not give the bios error. Even between exact same hdds with same fw that error would show. Ended up using a 10gb ide HDD with ez- …

I just ordered a 512MB CF card and a 2GB CF card, so fingers crossed one of them does the trick. When I get a chance, I’ll check the power supply with a meter—I read somewhere, though it was pretty vague, that voltage drops or instability might stop the hard drive from starting up right, leading to …

No unfortunately it doesn't let me change it at all. I'm leaning towards this CF-IDE device because it is admittedly a generic version of it from what I can tell, not sure who make more reliable ones. For all I know it could be the CF card itself. I don't have any known working IDE drives laying …
