Redhat 7.2 + 2.4.19 + VT8633 (those unitedcolo celeron 1.7 boxes)
hdparm -tT /dev/hda
And paste your results. If you get ~5 MB/sec for disk reads. Try
hdparm -d1 /dev/hda
And run the test again
I'm running Redhat 7.2 with 2.4.19 kernel. If I run the "hdparm -d1 /dev/hda" I get
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
My "hdparm -tT /dev/hda" results as follows;
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.45 seconds =284.44 MB/sec
Timing buffered disk reads: 64 MB in 10.68 seconds = 5.99 MB/sec
Disk read should be hovering around ~40. According to /proc/pci the ide controller is based on;
PCI bridge: VIA Technologies, Inc. VT8633 [Apollo Pro266 AGP] (rev 0)
Anyone with any luck getting it to `40? I've tried numerous configurations, even editing lilo.conf and adding append="idebus=66" because dmsg reports 33 in use. I also noticed the 2.4.19 kernel config lists only;
[*] VIA82CXXX chipset support
Dosen't list VT8633 though, maybe thats the problem?
My snippet of dmesg as follows;
VP_IDE: IDE controller on PCI bus 00 dev 89
PCI: No IRQ known for interrupt pin A of device 00:11.1. Please try using pci=biosirq.
VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: Unknown VIA SouthBridge, contact Vojtech Pavlik
hda: ST360021A, ATA DISK drive

Partition check:

Edit:
The harddrive is a 60gb Seagte Barracuda ST360021A model.
Warning don't try and add hda=ide-scsi in your lilo config as it will freeze the machine up on reboot. Well for me it froze.
