Hi! I'm using several Intel server boards with ServerWorks CSB5 chipset for IDE. Even though this chipset is supposed to support ATA100 and it is supposed to be supported in Linux and I do have CONFIG_BLK_DEV_SVWKS=y in my .config, I can't set speeds higher than 'hdparm -X66 /dev/hda'! This is what I get in my dmesg: Uniform Multi-Platform E-IDE driver Revision: 6.31 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ServerWorks CSB5: IDE controller on PCI bus 00 dev 79 ServerWorks CSB5: chipset revision 147 ServerWorks CSB5: not 100% native mode: will probe irqs later ide0: BM-DMA at 0x2840-0x2847, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0x2848-0x284f, BIOS settings: hdc:DMA, hdd:DMA hda: IC35L060AVER07-0, ATA DISK drive hdc: IC35L060AVER07-0, ATA DISK drive hdd: SONY CD-ROM CDU523 1, ATAPI CD/DVD-ROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=7476/255/63, UDMA(33) hdc: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=7476/255/63, UDMA(33) Is it just me or is someone else having the same problem?
