Freebsd.

sysctl og atacontrol er tydeligvis ikke helt enige.
# sysctl hw.ata
hw.ata.ata_dma: 1
hw.ata.wc: 1
hw.ata.tags: 1
hw.ata.atapi_dma: 1

# atacontrol cap 0 0
ATA channel 0, Master, device ad0:

ATA/ATAPI revision 3
device model FUJITSU MPC3064AT
serial number 38087041
firmware revision CC05
cylinders 13328
heads 15
sectors/track 63
lba supported 12594960 sectors
lba48 not supported
dma supported
overlap not supported

Feature Support Enable Value Vendor
write cache yes no
read ahead yes no
dma queued no no 0/00
SMART yes no
microcode download no no
security yes no
power management yes no
advanced power management no no 0/00
automatic acoustic management no no 0/00 0/00

Det som irriterer meg er at writecache, og readahead tydelivis er
støttet, men de er ikke enabled. Noen som vet hvordan det gjøres?

# cat /boot/loader.conf
# -- sysinstall generated deltas -- #
userconfig_script_load="YES"
hw.ata.atapi_dma="1"
hw.ata.ata_dma="1"
hw.ata.wc="1"
hw.ata.tags="1"
autoboot_delay="2"

uname: FreeBSD 4.7-RELEASE-p5
