So, been sorting all my stash... Tried to install two Athlons, one is a XP1500+, the other one is the XP2400+. The first gets recognized from the getgo, the latter instead needed some resets, it displayed unknown processor, but eventually went through the POST. Unfortunately I don't have an HDD installed at the moment.

I also found the intel counterpart of the KT7a-Raid, the ABIT BX133-Raid. That one is paired with a P3-750MHz. Ok, it has one PCI less, but as far as I read, it should be feature wise on the same level. Though I wonder if the intel chipset has less problems with PCI audio.

The KT7A is a much better choice than the BX133 and dare I say even better than K6/3+ because like K6/3+, it has multiplier adjustment but is a lot faster.

But if you are going to use PCI audio, then just use anything. The whole point here is the ISA slot for DOS compatibility.

Was just surfing the internets and found out that the BX133-Raid has a connector called SBLink or also PC-PCI. Its purpose is to improve compatibility by giving the card direct access to DMA and interrupt signals, thus mimicking an ISA card, when using PCI for audio. Of course you need a sound card with that connector too in order to be able to use it.

Yes, I recommend YMF744 or YMF724 for SB-Link and I can confirm excellent support for it.

Martin85, mockingbird,

The KT7A has no capacity or connectors for SB-Link. Why are you posting here? GTFO

The KT7A is a legacy board for folks who don't want PCI sound cards.

WTF is wrong with you?
