I did find a video where someone claims that one pin of the battery is on a real pin of the chip and you only have to drill one hole. https://www.youtube.com/watch?v=xBvw1TLHyqM If you drill the hole, consider making it big enough to clip off the old battery, otherwise you will drain the new one …

OK, I tried an earlier bios version. 2.30 gives me "ESCD updated". So that problem is solved. On the down side, I lose the ability to boot from CD etc. Seems like they changed the allowed bios chip ID in 2.31.

I reflashed the BIOS, which was on 2.31 already. The reflash worked, there were no complains about the flash type from the flash software. Yet the "unknown flash type " post message remains. My board revision is 3B. I wonder if the bios is too new for my revision. Pictures show a later revision 4. …

I have dumpstered an old GA-586ATE/P. The ODIN chip was empty, so I drilled for the contacts and soldered a 2032 battery to it. I accidentally broke off the lonely pin 1. I also replaced it with a staple, and detected +3V between pin 1 and battery minus. Seems the pin does connect. PC seems to work, …

I troubleshooted this a bit more today and found that it works fine with the lid off. Investigating further revealed that the reason the tray isn't coming out is because the sled inside isn't lowering. This is due to the disc platform getting suctioned up to the lid and not releasing. I'm not …

This is planned obsolescence. I have a Plextor drive, a heavy duty solid thing, evidently built to last, which has a direct mechanical linkage between motor and tray. Why aren't all drives built like this? Because then you wouldn't be forced to replace them every 3 years. (I assume my Plextor was …

The problem was the following in all of my cases: There is a thin belt in front of the drive, taking an egg shaped form. The belt will always rest with a sharp curve at the small spindle. The belt will adapt to the sharp curve form somewhat over the years and lose some traction. Slide the belt by …

An item is worth as least as much as you get for it! If you put it up for x and someone pays x, it evidently was worth at least x. So if you consult ebay, do not look for the offers but for the completed sales in the past. There you get an idea what people have paid in the past. And that is an …

Which version of 3Dmark99 did you use? Frame buffer? Resolution? I can run my Creative Labs V2 with 3Dmark99 max without problems. The non-max version does tend to have issues with many older 3d cards.

Does the card pass all 4 tests? You hear fm, internal wavetable and 8/16 bit SB? Is MIDI volume up in mixer? As a data point, I do own rev3 of the card, but had no "issues" using NEC XR385 on it. The card is noisy compared to later AWE32 models.

So then I guess my next question is... can we guess what the real CPU speed in there is? Sure: 200 MHz, at the time the picture was taken. But you want to know what the print on the cpu will say. Afaik, anything between 233 and 400 Mhz. (I have not yet seen a 450 MHz P2 with limited multi, but …

In some way of another, C64 development reminds me of the good old DOS days with QuickBASIC 4.5 and Turbo Pascal 6/7. Alas, it's easier to find C64 fans than DOS lovers these days. C64 is perceived as retro-cool, while DOS is lame. :sad: So it might be worth it to overcome ourself and look past the …

If I take myself as a sample point, I initially upgraded from a Pentium1 120 MHz to a Pentium II 450 MHz. As many Slot1 boards would not be upgradeable with Coppermines, they simply did not offer an easy x2 upgrade option. The next CPU I upgraded to was an Athlon XP. Coppermine simply was no option …
