Hi,
We have just obtained a Legend KuDoz 7 Motherboard which uses an Athlon
XP 1600
processor and has a VIA Apollo KT266 chipset (VT8366 and VT8233).
We have installed RedHat 7.1 with kernel 2.4.3-12.
In general the system appears to work fine apart from appallingly slow
IDE performance.
hdparm -t gives us the following performamnce:
/dev/hda:
Timing buffered disk reads: 64 MB in 28.22 seconds = 2.27 MB/sec
Info on the settings is:
/dev/hda:
Model=Maxtor 5T040H4, FwRev=TAH71DP0, SerialNo=T4J363CC
Config={ Fixed }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57
BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=-66060037, LBA=yes, LBAsects=80043264
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
/dev/hda:
multcount = 16 (on)
I/O support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 4982/255/63, sectors = 80043264, start = 0
We have tried different drives and tries setting different options using
hdparm to no avail.
We have also tried running ReadHat 5.2 (2.0.36) and this experiences the
same problems.
We note that if we try to do "hdparm -d1 /dev/hda" we get the message:
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
Any ideas ?
Cheers
Terry
