8600 DAV?

[avw]

I am playing with my 8600 recently and like to make it a productive machine again. As I got it very late (some day 2005 or something, and didn´t use it very often as I had my Umax S900 back than) I don´t know the motherboard very well. Now I tried to understand everything. So what is the DAV connector exactly?

I found the info that it is for "faster graphic- or video cards", but no info what it exactly is, and no info what cards existed. I also don´t kow if its a single connector, or used by cards additionally to PCI?

Ah and one further question, the cache slot is normal processor cache like at all onborad macs? So better to kick it, when using G4 upgrade cards? There is no difference to any other "Oldworld machine" that makes the cache slot interresting beside a G4 cache at upgrade cards?

I am not sure about what cards, if any, used the digital av slot, but the cache slot is only useful if you are still running one of the original 604e processors. Go to a G3 or G4 and you can't use the logic board cache.

The AVID Cinema card (video capture) used the DAV slot. That slot is connected to the AV ports on the 8600 so an add on card can bypass the built in AV chips (there is a fat cable connecting the slot to the card). Most people just purchased a decent 3rd party PCI card for video capture and didn't use the DAV slot at all.

Some of the 8600's (604EV processor 300Mhz+) had cache on board so the cache slot on the motherboard was not used. Anybody adding a G3 or G4 upgrade CPU didn't use the cache slot on the motherboard at all (caused stability problems).

OK fine. So the cache situation is the same as with my 6100, 9600, ...

Good, the DAV is the "Digital AV slot". But I didn´t understand that "bypassing feature". There are those AV onboard connectors ( S-Video, Composite, Stero Sound IN/OUT), including the DA/AD converters somwhere onboard. Did I understand you correctly, that those DA/AD converters can be bypassed with DAV? Or are they than directly connected to such a DAV enabled card?

I still don´t understand if it is an PCI card with additional DAV connector, or a "DAV only" card if it uses the slot?

And of course I got a 128 MB Radeon 9200 for day to day usage now.

The AVID Cinema card is a PCI card with a cable that plugs into the DAV slot.

Would that by chance have any relation to this output-only card?

Its probably that card, mine is installed in a 6500 so I can't verify. They are nothing special.
