According to Civilme, mandrake 8 shuts off udma 66 or above on motherboards with the 686 southbridge chip,, and that chip is on every KT133 motherboard I have seen thus far... (it does this to stop a bug in the chip causing you to lose data.) Bet thats your problem, I am waiting for Mdk8.1 to come out in the hope that one of those smart buggars works out a way to work around the problem.. I am in a worse position becaus I have a 7200rpm WESTERN DIGITAL hard disk... and they suck apparently... although on mdk7.2 I get around 29mb/sec on hdparm tests, which apparently isn't that bad.,.... as soon as I find someone to upgrade to my hard drive, I will get an IBM 30 gig or something,,, (probably around the same time that MDK8.1 comes out...) regards Frank -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Stephen Poynter Sent: Wednesday, 4 July 2001 8:12 AM To: [EMAIL PROTECTED] Subject: [expert] udma 66???? Hey everyone, I'm having a little problem getting mandrake 8 with the stock kernel to use my hardrive in udma 66 mode. In the dmesg log it looks as though my udma controller is recognized properly, but when the hard drives are detected it shows them as using only UDMA 33. I have an Epox-7KXA with the KX133 VIA chipset and a Maxtor 20GB ATA66 hard drive. Any suggestions on enabling UDMA 66???? demesg output: ---------------- ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx 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 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx VP_IDE: VIA vt82c686a (rev 21) 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:DMA hda: Maxtor 52049U4, ATA DISK drive hdc: WDC AC33200L, ATA DISK drive hdd: ASUS CD-S500/A, ATAPI CD/DVD-ROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: 40020624 sectors (20491 MB) w/2048KiB Cache, CHS=2491/255/63, UDMA(33) hdc: 6346368 sectors (3249 MB) w/256KiB Cache, CHS=6296/16/63, UDMA(33)
