I have a problem to allow DMA setting to my harddisk. I have Toshiba Satellite 320CDT laptop. I found this question in letter's archive: http://search.luky.org/linux-kernel.2003/msg35013.html And the answer: http://www.ussg.iu.edu/hypermail/linux/kernel/0306.0/0308.html This is part of my dmesg from 2.4.26 kernel: ......... Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx hda: TOSHIBA MK4006MAV, ATA DISK drive hdc: CD-220EA, ATAPI CD/DVD-ROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: attached ide-disk driver. hda: host protected area => 1 hda: 8007552 sectors (4100 MB), CHS=7944/16/63 hdc: attached ide-cdrom driver. hdc: ATAPI 20X CD-ROM drive, 128kB Cache Uniform CD-ROM driver Revision: 3.12 Partition check: hda: [PTBL] [993/128/63] hda1 hda2 hda3 hda4 ............ I know that is problem with bridge used for ide handle. I tried a lot of kernels: > 2.4.26 and 2.6.10 series. Please tell me with patch will solve my problem for 2.6.10 kernel or what can I do for enabling DMA? Another question: In my bios I can choose two variant for my IDE: * Standard IDE * Enhanced IDE Which should I choose? I tried both and I dont's see any difference. Sorry if my english is poor.
