It is very feasible to run FreeBSD/i386 on AMD64 hardware. I encourage you to go ahead and move to AMD64 hardware regardless what version of FreeBSD you decide to run for now. You will get excellent performance, and you will have a 64-bit upgrade path when you decide to move 32-bit -> 64-bit. > >Here's what we're proposing for the new hardware: > >AMD Athlon64 - 3200+ (Socket 754 - I know, but it's cheap) > >MSI K8T-FSR (VIA Chipset) > >Adaptec AAC-2410SA 4-Port S-ATA RAID Controller > > This one is gonna be tricky on you, I think.

I have repeatedly asked if anyone > will step up to the task and fix that, You're really exaggerating here. There are two families of Adaptec RAID controllers -- aac and asr. 'aac' family controllers are quite popular and are the higher performing of the two families. The AAC-2410SA 4-Port S-ATA RAID Controller uses the aac(4) driver and the driver very much works on 64-bit machines. > as I have an Adaptec Zero-Channel RAID add-on-board for my dual opteron > just collecting dust at the moment, but the general answer is 'no > time'... Too bad. The Adaptec Zero-channel products are from the other product family. That particular driver has issues. -- -- David (obrien@FreeBSD.org)
