Has anybody ever done or considered using FreeBSD for VME IO solutions? We're looking into Pentium-based Single Board Computer that drops into a VMEbus backplane. One board, that we have in-house for another project, is the General Micro Systems V254 Mustang. It's got dual P166 with on-board Ethernet and SCSI (DEC 21140 and Adaptec 7880 UW). I booted FreeBSD on it and it recognized everything, but I haven't had time to do an install and play around on it anymore. The VMEbus is interfaced to the PCI bus by the Universe VMEbus interface chip made by Tundra (formerly Newbridge Microsystems). Luckily, all the manuals for the chip are available at Tundras web site (http://www.tundra.com/Tundra/Products/Bus/BPI/Universe.html). How hard would it be to create a VMEbus driver for this? The project under consideration would only need to memory map VME devices, but having the ability to config a VME device at an address and VME interrupt priority/vector would be great for future work. Thanks, Dan Eischen deischen@iworks.InterWorks.org
