Well, "noname" was more in the sort that its not a "brand name" machine, but one build out of garden varity parts. It's a TYAN s1662D dual PPro board with dual P6/200/256K, memory is 4 stock 32Mb 72pin 60Ns EDO RAM. Timing is set as std for the 4.0E BIOS with 60Ns memory timing, disks are two Maxtor DiamondMax 4.3G in DMA mode. I havn't run the CT benchmark, I'd have to find a DOS disk somewhere to do that. On the whole TYAN is know to have a much more agressive memory timing than say ASUS, and the board is pretty picky about RAM quality (I use Hyundai here). Worldstone (a WHOLE world with -j9 -O -pipe and src & obj async on different disks) on this machine is ~1h10min dependend on how much happens in between (it runs X during the make as I have no text console :) ). -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Søren Schmidt (sos@FreeBSD.org) FreeBSD Core Team Even more code to hack -- will it ever end ..
