Greetings, I had installed 8 x 32 MB parity SIMMs in an Asus P65UP5 Rev. 2.04 mainboard with Pentium Pro card P6ND in it. The system is equipped with one PPro 200 CPU. Unfortunately, when I install 4, 6 or 8 of these SIMMs, FreeBSD gives me a parity error and panics directly after the copyright notice during boot. With 2 x 32 MB, it seems to run OK. This, however, happens only when I enable ECC in the BIOS. When I disable ECC/parity, the system runs fine with 256 MB installed. I made world on the latest 2.2-stable in this configuration, no problem. I also tried the same SIMMs in a Gigabyte 586 HX board, and there I can boot and run just fine with ECC enabled in the BIOS (it's an NT system, though). Any ideas ? It doesn't look to me like the SIMMs were faulty. Maybe a problem with the parity chips ? I also exchanged the mainboard with another one of the same type, but found the same problem. Michael
