Well, Linux proved that wrong. I installed an Intel EtherExpress 10 in an Olivetti ISA/PCI machine and had the same problems with FreeBSD 2.1. Finally I went into the BIOS setup and disabled the PCI/ISA buffer cache (or something like that). Since then it seems to be much better. 3 timeouts in the last 3 days of operation with the following packet rate: Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll ix0 1500 <Link>00.aa.00.53.14.4e 1094735 0 566359 3 2238 Before I got timeouts every time I tried to even ftp a file bigger than 50K. Now it's probably doing close to 100MB a day of traffic in & out. A 3Com 3C509 in the same machine hasn't given me any timeouts, but the docs say that driver is supposed to be buggy. Raju -- Raju M.
