This is BIOS on my new vprMatrix 175B4 notebook (P4M-1.7GHz). Along with ATA, it "forgets" to enable ports on network card (fxp driver), I've already committed patch for it. Funny thing is that the problem doesn't exists on 4.7 - both ata and fxp work here OOB. This might be somehow related to ACPI, but forcefully disabling it in 5-CURRENT doesn't help. Anyway, this option is "off" by default, so that there should be no problems for average Joe luser, while I have not noticed any problems with this patch for far - both UDMA100 disk works perfectly so as CD-RW/DVD drive. -Maxim
