Normally the probe looks like: FreeBSD 4.4-RC #7: Tue Aug 28 07:14:11 EST 2001 =2E.. atapci0: port 0x1000-0x100f at device 20.0 on = pci0 atapci0: Busmastering DMA not supported ata0: at 0x1f0 irq 14 on atapci0 ad0: 3102MB [6304/16/63] at ata0-master BIOSPIO acd0: CDROM at ata0-slave using BIOSPIO But if the BIOS accesses the HDD or CD-ROM, then the HDD probe returns nonsense - for example: ad0: 43403MB <=FFP=FF=01=FFQ=FFQ=FF=10=FFP=FF=10=F7@=F7 =F7 =F7 =F7 =F7 =F7= =F7 =F7 =F7 =F7 =F7 =F7> [65360/80/17] at ata0-master BIOSPIO According to pciconf and /usr/share/misc/pci_vendors, the controller is an OPTi 82C825. Also, I notice that the generic bus-mastering DMA code doesn't pick this as a DMA-capable controller. According to both the Compaq configuration software and the pci_vendors document, the controller does support bus-mastering, so I presume some device-specific setup is needed. Does anyone know how to enable bus-mastering on this device? (OPTi don't list it in their `full IC listing').
