Force ATA66

[Alejandro González Hernández - Imoq <imoq imoqland com>]

Hi!

I have an IWill motherboard, that supports ATA-66 HDD's, and also a hard
disk that supports it as well. It seems that the kernel does recognize
the controler:

VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: chipset revision 16
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt82c686a (rev 22) IDE UDMA66 controller on pci00:07.1
    ide0: BM-DMA at 0xd000-0xd007, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xd008-0xd00f, BIOS settings: hdc:DMA, hdd:pio
hda: WDC WD400BB-60BNA1, ATA DISK drive
hdc: SAMSUNG CD-R/RW SW-408B, ATAPI CD/DVD-ROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15

However, it also seems that the drive is used as ATA33:

hda: 78165360 sectors (40021 MB) w/2048KiB Cache, CHS=4865/255/63,
UDMA(33)

I can use the "ide0=ata66" parameter in lilo to force it to UDMA(66),
however, I get so many warnings in dmesg when I do this (altough it
finally says UDMA(66)) that I'm afraid I could damage somehow my system.

Do you think I should use the "ide0=ata66" parameter to force it, or
just leave it as ata33? It's my home system, anyway.

Thanks for your comments :)

Alex.
