This can clock PCI at CPU/2. By default, with CPU at 40MHz, PCI runs at 20MHz. However: I have tried setting CPU:PCI to 1:1, so PCI is clocked at 40MHz, and everything seems to work fine. So far at least. I have an AHA-2940 and a Diamond Stealth 64 (S3 968). I haven't done any benchmarking to compare the performance. Any comments on the wisdom of this? -- Iain Baird Network People International Tel: +44 (0)1732 743591
