FreeBSD will not use the SRAT table, but with it ON/Enabled/AUTO I know the CPU will be set up a certain way that we do want. > HPET Timer -> Enabled > ECC -> Enabled > DRAM ECC -> Enabled > ECC Scrub Redirection -> Disabled I would turn on ECC Scrub Redirection, but thats just to gain reliability. I would also download the latest memtest86+ ISO image from www.memtest.org, burn it to CDROM, and see if all your RAM passes. I assume it is IBM [re]branded? -- -- David (obrien@FreeBSD.org)
