I do have an 1820A, and the reason I chose that over the standard 1820 was the onboard processor. Sorry about the confusion.

My problem is that I can't just throw something out if it still works, so I try to make use of it until it dies, and then I can justify buying something new (however, by the time this board dies, I'll most likely have inherited some other slightly newer still working board without 64-bit PCI, and I'll be forced to use that until it dies... :) ). That's the primary reason I went with this board, that it would work in what I already have, and should work for a time to come with whatever I do end up getting. I did splurge on a new Dual Xeon setup which will be for video encoding, but I have a SCSI subsystem for that machine, and I needed the horsepower. > > Tulio G. da Silva > -Gary
