Re: [Nolug] DMA ?

I am running 2.4.19 from the distro. The set dma for disks only is
something that I put in the kernal trying to get dma to work. It did
not help.
I set 32bit and unmasqirq as you suggested and ran hdparm -d1 -x67
/dev/hda it comes up with :
plt@chon:~$ su
Password:
root@chon:/home/plt# hdparm -d1 -x67 /dev/hda
-x: missing value (0/1)

hdparm - get/set hard disk parameters - version v4.5

Usage: hdparm [options] [device] ..

Options:
 -a get/set fs readahead
 -A set drive read-lookahead flag (0/1)
 -b get/set bus state (0 == off, 1 == on, 2 == tristate)
 -B get Advanced Power Management setting (1-255)
 -c get/set IDE 32-bit IO setting
 -C check IDE power mode status
 -d get/set using_dma flag
 -D enable/disable drive defect-mgmt
 -E set cd-rom drive speed
 -f flush buffer cache for device on exit
 -g display drive geometry
 -h display terse usage information
 -i display drive identification
 -I detailed/current information directly from drive
 -k get/set keep_settings_over_reset flag (0/1)
 -K set drive keep_features_over_reset flag (0/1)
 -L set drive doorlock (0/1) (removable harddisks only)
 -m get/set multiple sector count
 -n get/set ignore-write-errors flag (0/1)
 -p set PIO mode on IDE interface chipset (0,1,2,3,4,...)
 -P set drive prefetch count
 -q change next setting quietly
 -r get/set readonly flag (DANGEROUS to set)
 -R register an IDE interface (DANGEROUS)
 -S set standby (spindown) timeout
 -t perform device read timings
 -T perform cache read timings
 -u get/set unmaskirq flag (0/1)
 -U un-register an IDE interface (DANGEROUS)
 -v default; same as -acdgkmnru (-gr for SCSI, -adgr for XT)
 -V display program version and exit immediately
 -w perform device reset (DANGEROUS)
 -W set drive write-caching flag (0/1) (DANGEROUS)
 -x perform device for hotswap flag (0/1) (DANGEROUS)
 -X set IDE xfer mode (DANGEROUS)
 -y put IDE drive in standby mode
 -Y put IDE drive to sleep
 -Z disable Seagate auto-powersaving mode
root@chon:/home/plt#

This is what I got after:
root@chon:/home/plt# hdparm -v /dev/hda

/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 = 2498/255/63, sectors = 40132503, start = 0
 busstate = 1 (on)
