I've run 8400s up to 2GB. Any more than that and you'll find that S/G DMA hasn't been finished ;-). Also, haha, you'll find that ECC errors aren't corrected, since TLASER screwed the pooch wrt ALPHA spec and requires you to run around and fix ECC errors induced by the I/O boards. Since I now, for the first time in 4 years, have a real external customer who actually might run TLAser, I guess I'd better finish this, hadn't I? -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
