All sort of weird problems can arise, anyhow... for example, I upgraded a Shuttle HOT-419 to 512 kb single-banked cache, jumpered it accordingly, yet the ONLY program that sees and can test the L2 cache is Speedsys. CTCM, Cachechk and the likes ALL report NO cache present... CTCM? Please excuse my …

Usually if the wrong cache jumper settings are set, you'll get HIMEM errors. Normally, when the cache is not seated properly, you'll also get HIMEM errors. Either the cache is fake (though it looks genuine), or it is somehow disabled, via a jumper, or in the BIOS. I see what looks like a 256 KB for …

Does cachechk need to be run from a clean boot (i.e. no config.sys or autoexec.bat) to work properly?

Yeah I just picked up a bunch of 12, 15 and 20ns cache on ebay today for $10 theres still some on ebay from that ukrainian dude I think. From what I have read on vogons: look for a company logo on the chips, correct font and part numbers and Im guessing anything from 10ns to 25ns will be fine ( …

Warm, but I wouldn't say hot. According to the BIOS settings it should be enabled. But I'll check it again. Who knows, I may have missed something. Wondering about just buying some new cache chips. I assume it's alright to use a different brand, as long as they are same spec chips? No errors from …

Are the cache chips fake? Do they haves traces and are connected? or is it something simple like a jumper setting/bios setting or they just need to be extracted and re-seated? Have a good look at the pins and reseat them carefully. Cache chips are labeled "W24512AK-15" on the top line and below …

Same results from Cachechk when L2 is set to WT. Does anyone have any good ideas as to what may be causing this?

Yeah, I was wondering about that. I got the distinct feeling that there was something funny with the memory benchmarks there, but I've done multiple runs and they all come out the same. I dunno if I have to run my cache at WT mode, seeing as I got 64MB ram and only 256KB cache. Maybe I'll try to run …

I figured I'd post my Speedsys results. Don't know if they are what they should be, but I'm sure somebody would know. I'm wondering if I'd gain any noticeable performance by getting an Intel DX4 instead.

Aye, I decided to do just that. Had another look at them and gave them a go. Sorted the graphics issues. I've been waiting a few years to finish this game. Thanks 😀

My italian is a bit rusty, but from google translate it seems these patches are mainly for running the game under Windows XP? I've downloaded SDD though, and I'll try it tomorrow. If that doesn't work, I'll try with my Trident 9440 graphics card.

Now that my 486 is up and running, i felt it was time to install some classic games, so I got out my bigbox of Ripper. Game installs just fine but when I start playing, I get some weird graphical bugs. The about half of the time, the whole game screen, aside from drop down UI, is squeezed into the …

A'ite, seems the SB EMU from the GUS drivers was hogging irq5. I've changed the SB16 irq to 10 now and it's working perfectly. Just played a few tunes in FT2 and played a few levels of Tyrian, and sound was as flawless as such things get on this old hardware.

Which method did you use to attach the heatsink to the cpu? The heatsink came with a heat conductive sticky-pad. It's the thinnest sticky-pad I've seen so far, and it seems to conduct heat well enough for a 486. The heatsink cost something like £3 on Amazon, and I got free delivery, so it was …

I haven't seen a machine earlier than a Pentium that detects a CD ROM at the bios level. The driver will still find it. I'm able to boot from a boot-able CD ROM on my 486 but only due to the fact I'm using SCSI. But yeah I don't know of any pre-pentium machine that will detect your CD ROM at bios …

I'm fully aware that DOS require drivers for any device you want to use. I guess I've just gotten so used over the years to the BIOS also having to detect the presence of the devices as well. Like, if a more modern pc (and by more modern, I mean post-socket7 or so) doesn't report a device during …
