Subject: More ATA100 oddity
Date: Thu, 19 Apr 2001 09:36:09 -0700 [thread overview]
Message-ID: <20010419093609.A7170@petreley.com> (raw)
I just noticed something odd. (I'm using 2.4.3-ac9 on an
ASUS A7V, Athlon 1000 mHz)
(1) As noted in other messages, my machine boots up the Promise
chipset as UDMA(100)
hde: 80041248 sectors (40981 MB) w/2048KiB Cache, CHS=79406/16/63, UDMA(100)
(2) hdparm recognizes it as UDMA5 with 27 MB/sec speed
/dev/hde:
Model=Maxtor 54098H8, FwRev=DAC10SC0, SerialNo=K80EP5NC Config={ Fixed }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57
BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16,MultSect=off
CurCHS=16383/16/63, CurSects=16514064, LBA=yes,LBAsects=80041248
IORDY=on/off, tPIO={min:120,w/IORDY:120},tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5
Timing buffered disk reads: 64 MB in 2.31 seconds = 27.71 MB/sec
(3) /proc/ide/pdc202xx sees it as UDMA 4
PDC20265 Chipset.

Oh, and by the way, ACPI support has never powered off this
machine. Ever. But I use apm and I'm happy.
