SAMBA - rychlost [DMA na disku s ALI chipsetem]

[Martin Lipinsky]

Neni nahodou problem v tom (i kdyz linux by mel na nastaveni v biosu
kaslat):

BIOS settings: hda:pio, hdb:pio
BIOS settings: hdc:pio, hdd:pio

?

Ja mam na stroji:

ICH5: chipset revision 2
ICH5: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xfc00-0xfc07, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xfc08-0xfc0f, BIOS settings: hdc:DMA, hdd:DMA
hda: IC35L040AVVA07-0, ATA DISK drive

atd ...

Navic kdysi na starem intel chipsetu mi to sice pri zapnuti DMA vypsalo
podobbbnou chybu jako ted pisete ... ale pak to behalo ... bohuzel se k te
masine ted nedostanu, byl to starecek s P75.

V dalsim mailu pisete ze hdparm dava:

hdparm ukazuje 4,19MB/s a 96,55MB/s

Kdyz date hdparm -d0 /dev/hdc a zmerite to znova, nebudete tak na polovine
? Podle me to znamena ze DMA Vam bezi, bohuzel z toho cipsetu vic
nedostanete.

(co rekne hdparm -d /dev/hda ?)

S pozdravem
