... not that VLB didn't suck badly with several devices attached at the same

"6 VLB slots!!!" touted by marketing...

I can't find VLB specs online, but IIRC 3 had been the limit and anything
past that had been very much out of spec and likely to screw you.

I think that particular board had multiple root drivers (it was a P5 board, so it wasn't a "local" bus anyway.)
