It may be the case that FreeBSD 4.9R cannot use ATA 133 on the VIA 8237. I saw 8.10 *does* support the via 8237. I'm unclear as to whether it also supports the ATA 133 modes (hardware notes say: VIA 8237 SATA150). Is there a way I can just upgrade the ata driver, without going all the way to 8.10? I really cannot continue with using WDMA2 on 16 MB/s. That is about ten times as slow as it can be! I appreciate the help, - Mark
