Any updates on this project, Hard1k? I completely understand if its shelved/on-hold between COVID-19 still being bad and needing to get the Awe64 Legacy cards built and out the door, but I am curious.

Something like the PCI to ISA bridge might work with a sound card on an Intel ICH5 or earlier platform. ISA sound requires DMA, and Intel removed DMA functionality from later chipsets. I can't speak to AMD chipset compatibility with DMA, I'm afraid. The bridge chip would need to support DMA as well …

Wonder what heat level expected, how safe it will be for compact cases that have not so effective cooling or not have it at all? CM4 should have 6.5W TDP at the worst. The heat it generates should only really be a concern for the CM4 itself, and nothing else in the case. Running MT32 Pi or a …

This has the potential to be a massively powerful card. The RPi CM4 is quite powerful for an embedded device and can even be equipped with up to 8GB of RAM on board. Even outside of MT-32, it should be able to handle running as a soundfont synth pretty well.

There appears to be solder pads for SB-Link on the Intel D850EMV2. Its the right configuration of pins and given its proximity to the ICH2, I'm inclined to think its PC/PCI. Filename s-l1600.jpg File size 468.99 KiB Views 550 views Filename D850EMV2 PCPCI.PNG File size 1.3 MiB Views 550 views

I think the idea of building new boards for 486 or even Socket 7/Super 7 Pentium and K6 is a great idea but, like the NuXT, I think as much readily available hardware should be used as possible. Building an FPGA for large-scale integration is no simple task, and having to handle the complexities and …

This is odd. The only reason I can think of it might happen is there is some firmware on the card that dis-allows certain processors. The only reason I can think of they might do that is to prevent overloading (over current) the pins in the CPU socket or maybe the traces on the adapter card. That …

Okay, so, some corrections to make and some yet stranger results coming out of this board. As it were, the Tualatin Celeron I did get to work isn't a 1400mhz, its a 1300mhz! With further testing, the 1300mhz works at its intended voltage and works darned well. What makes the situation even weirder …

When you say AGP performance is godawful, how awful are we talking? Would it make a difference for 3DFX cards that only use the AGP slot as a glorified PCI slot? Also, is that ISA slot DOS compatible? Anandtech did a review of the HEsl chipset (which is kind of a refined version of the HE, AFAIK) …

Possibly Ethernet related? SMC makes network adapters... Searching Google for "Mini_SMC" found a newer (laptop?) port replicator schematic which used "Mini_SMC" where SMC stood for SMBus clock, I think... I'd have to agree with this, SMC almost always refers to the System Management bus, I can't …

4GB in anything with a 440BX or 440GX chipset is plainly impossible, the memory controller just isn't up to the task.

A bit of a strange question, but something I'm wondering about for a project I'm working on. Does the AGTL P6 bus require that the board be set to the FSB of the CPU in order to work at all, or can lower FSBs be used? For example: Say if you had a dual slot 440BX board, like a P2B-D, and you wanted …
