Имеется не очень новая мамка на via686 (Dual PIII).
На ней набортный АТА-100 контроллер и два винта на разных шлейфах:
PDC20265: chipset revision 2
PDC20265: 100% native mode on irq 18
PDC20265: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER
Mode.
ide2: BM-DMA at 0xb800-0xb807, BIOS settings: hde:pio, hdf:pio
ide3: BM-DMA at 0xb808-0xb80f, BIOS settings: hdg:pio, hdh:pio
Probing IDE interface ide2...
hde: ST3200822A, ATA DISK drive
ide2 at 0xa800-0xa807,0xac02 on irq 18
Probing IDE interface ide3...
hdg: ST3120024A, ATA DISK drive
Винты работают как-то не очень быстро:
[root@threebears root]# hdparm -t /dev/hde
/dev/hde:
Timing buffered disk reads: 60 MB in 3.01 seconds = 19.93 MB/sec
[root@threebears root]# hdparm -T /dev/hde
[root@threebears root]# hdparm -t /dev/hdg
/dev/hdg:
Timing buffered disk reads: 54 MB in 3.06 seconds = 17.63 MB/sec
А при копировании с винта на винт 7-12Мб/с (по данным mc).
Это нормальная скорость? Вроде как побыстрее должно быть.

Написано ж - pio.
hdparm -d1 /dev/hde

Угу, блин. Перекосило что-то в системе. Заглянул в /proc/interrupts, а там:
[root@threebears proc]# cat ./interrupts

А не тесно ли двум винтам, USB и сетевухе на одном прерывании? Можно
их как-нить раскидать по разным? Переставить все что можно в дрегие
слоты?

Эффект не проявился:
[root@threebears root]# hdparm -d1 /dev/hde
/dev/hde:
setting using_dma to 1 (on)
using_dma = 1 (on)
[root@threebears root]# hdparm -i /dev/hde

[root@threebears root]# hdparm -t /dev/hde
/dev/hde:
Timing buffered disk reads: 62 MB in 3.04 seconds = 20.38 MB/sec
Кстати, *udma5 всегда было но обоих винтах. Так что вроде не PIO.

Маловато. У меня для этого же диска 48.93 MB/sec на плате VIA
C3M266.
