I had several with BOTH, with NO problems! The problem is that you can detect memory misconfigurations, SIMM contact problems etc. easier if you get it announced as a parity error. Without parity, all you get is (eventually) a segmentation fault, or a page fault while in kernel mode panic (or however these things are called in other operating systems). Then you never know whether it was a software problem or bad hardware. Btw., panic does even try to flush the disk buffers, so its effect is not as desastrous as you describe unless the disk subsystem itself is hosed. But in this case, you lose anyway. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
