Hello all,

Please accept my apologies if this question has already been answered....

I have a new Pentium 4 computer and I can't get the DMA working for hard
disk transfers.  Specifically, its a Dell Dimension 4500 with a Pentium 4
2.26 GHz processor (Northwood) and an 845 (Brookdale) chipset.  RedHat
7.3....

I noticed that the hard disk transfers were very slow.  I tried to set up
DMA with hdparm - see below:

[root@yoda ide]# hdparm /dev/hda

/dev/hda:
 multcount    = 16 (on)
 I/O support  =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 4866/255/63, sectors = 78177792, start = 0
 busstate     =  1 (on)
[root@yoda ide]# hdparm -d1 /dev/hda

/dev/hda:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma    =  0 (off)
[root@yoda ide]#

I thought that perhaps the chipset had changed between this Northwood
machine an the older core - I have a P4 1.8 GHz machine that DMA works fine
on.  I upgraded to kernel 2.4.19 with no change.

The IDE controller (according to Windows XP....) is an Intel 82801DB Ultra
ATA Storage Controller - 24CB.  I've included the lspci --vvx listing from
the problem machine below - my aplogies for the long list.  If anyone has
any suggestions I'd really appreciate them...

Thanks....

Mark
