Opp's the link is dead for my post .
Here is the info .
Then the reason is probably that your IDE drives are in PIO mode
instead of DMA! Remedy? Enter the device manager by right clicking
"my computer" and choosing "properties" and then
"hardware".
Double click on the "IDE primary drive" and then "advanced
settings". There you can see the current setting for the master and
the slave drives on the primary IDE channel. There you can select
transfer mode. If it is set at "PIO only", then select "DMA if
available" instead and reboot!
If the computer persists on having only PIO after reboot even though
the hard drive is a flashing super-duper ATA133 and transfer mode set
to "DMA if available", then you have to do the following:
Remove the primary device in the device manager and reboot! Voilà, now
the harddrive should be running in DMA mode.
Repeat on the secondary IDE channel if necessary.
