Have you sent one of these to Phil (or anyone else) for review? I had no idea this thing even existed until I was accidentally sent an email when inquiring about a PC MIDI card.

Is there a Mr. BIOS for the Intel NX chipset? (Or whichever one is the Pentium 60/66Mhz chipset)

Another update, for those who might be interested. I got the IPC chips swapped, but that still didn't cure the problem, though I did notice one of the LEDS on the POST card that wasn't lighting would occasionally come on now. So I looked again, and lo and behold, there is an honest to god discrete …

Well, I stuck what I believe to be a 100NS delay line in that socket, and it still won't boot at 33Mhz. While I haven't ruled that out as being the sole cause of this, given the flaky behaviour at 25Mhz with a 40NS delay line chip, I believe there is more to this issue, and I already have a new …

Minor update. Got the DS1000 up off the board, but I somehow managed to break three of its legs off. Got a socket down and tried a compatible chip from another board (one of those bigger, blockier types) with 40NS delay. It tries to boot with that, but it's gets stuck with 0A on the POST card. I …

Well, I can at least eliminate that theory. Doesn't boot at 33Mhz with the Mr. Bios either. It also eliminates a secondary theory about the eproms being too slow.

I'm also wondering if there is a check built into the BIOS that checks the CPU speed. I doubt it, as I think only IBM did that.

Yep, 50 and 66 mhz crystals here. 80 on the other boards. Ram is 60ns. ISA bus is supposed to be fixed at8mhz and is probably 8.33, but I have not pulled out ny counter to check it. Please post a picture of your board. Being the board name is: Micronics DX25 I am guessing it was not designed to run …

Hmm.. changing crystals on many old boards usually meant changing some jumpers to divide the ISA clock to make sure it still at 8mhz and sometimes also changing memory timing. Many old boards used the crystal to establish a base but others also used it to time many other things. Simple math: 50Mhz …

You changed the CPU, but you might still be running other parts out of spec. You'd better try to get your motherboard manual to see what the jumpers do. That's what I figured, which is why Iwas looking at that time delay chip. There aren't a huge amount of jumpers, but I am still playing with it. …

Board is a Micronics DX25, discrete logic board. Stuck a Dx33 in it and changed the crystal to a 66Mhz crystal and it simple won't boot, post card displays no numbers. I put the 50mhz crystal back in and it posts just fine. Never seen this happen before. The boards seems to be mostly PALs and …

I just did that and it did indeed work. Thanks for your help. In the end it didn't matter because the card will not accept the drivers for Windows 95. I may trie forcibly installing them later but I'm too disgusted with this and other issues at this point. Such is this hobby.
