Hi there. I seem to making use of rather of a lot of your time these days, so I'll try and keep it brief. I have an EISA box, and have built a custom kernel to suit my kit. The bus controller is configured as an isa0, with the various system devices hung of it. I am aware of the inherent limitations of the ISA setup (the 16M DMA address space limit, 16 bit transfers, interrupt management etc.), and was curious originally to see if there was explicit EISA bus controller support in FreeBSD the way there is for PCI. From the bridge chip sets being used on modern high-end server machines which give combined EISA/PCI bus capability, it would seem to me to mean that explicit EISA bus controller support would be an interesting way for FBSD to go. However, on reading the READMEs and docs, it appears as if there's not so much available. FINALLY, I get to the point ;) - I was scanning the hackers list a while back and came across a thread relating to WIP on a driver for the 3COM 3C579 EISA ethernet card. There was a reference to a kernel configuration line using a bus controller keyword eisa0. Excitement! Does this mean that there is WIP on EISA bus controller support and support devices? Any info would be greatly appreciated! -- Happiness is a smoking processor....... Rob Schofield M.Sc. AMIEE schofiel@xs4all.nl http://www.xs4all.nl/~schofiel
