Personally, I have beaten the snot out of Intel PIIX3 DMA 2 (WDMA2), 16 MB/sec Intel PIIX4 Ultra DMA 33 (UDMA2), 33 MB/sec Promise Fasttrak-66 Ultra DMA 66 (UDMA4), 66 MB/sec since 4.0.. No problems what so ever, although I have only used the promise for a month or so. You might want to look specifically for your controller chipset in the STABLE archives to see what others have experienced. ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Network Administration, mike@sentex.net Sentex Communications www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
