I bounced my last due to an aliases screw up -- Bill I've been fighting memory problems ever since I pulled out my motherboard and installed a new one. Unfortunately, the new one didn't work -- so I put back the old one. (The simms never came off it when it was pulled -- so I expected no problem... however, it's now sig-11, sig6 city. Dos based memory tests show nothing (I've got 20 meg... my best diag doesn't test past 16). FreeBSD boots, runs, and sig-11's occasionally during make world and heavy X stuff. I went from 20 meg to 8mb of 1mb simms -- same problem. I went to 16mb of 4mb simms -- same problem. I reseated and enabled and disabled the cache... same problem. I swapped in a DX2/66 to try to see if the problem would show up or go away with a CPU reseat/replacement. No luck. I'm waiting for the new motherboard -- and I have new 72 pin simms for it. (It's en route from the company as a swap with the bad one.) Anyone have a memory test recommendation that works short of a hardware memory test. I remember FreeBSD 1.5 pulled out errors on my wife's box that were causing crashes under OS/2 and SIG11's under Linux. I sure miss minicomputers with real memory controllers with memory address registers that latch parity errors and report the address. I sure miss BSD on a Vax that reported the ECC location and correction bits...
