You need to set them in your .config file before compiling it. Another procedure to turn UDMA on is to add #custom part # set drive hda to use UDMA [ -x /sbin/hdparm ] && /sbin/hdparm -d 1 /dev/hda # set drive hdc to use UDMA [ -x /sbin/hdparm ] && /sbin/hdparm -d 1 /dev/hdc #end custom part in your '/etc/init.d/bootmisc.sh' file - requires package hdparm. I have set up one machine with the modified bootmisc.sh using a regular Debian kernel image and one with a custom kernel with the above settings in .config. Both works great! Bye, Steffen
Re: Help for the UDMAmentally challenged ...
All that's there ... about the only wrinkle I have that perhaps I should have done differently at the very start is I left both disks on 'cable select' rather than explicitly choosing a master/slave. Anyway while I'd love for it to 'just work' I've added a udma100_setup.sh script to my init.d that runs the hdparm commads to start the drives -- to my mind, still a kludge, but hey it works.

Re: Help for the UDMAmentally challenged ...
I used hdparm -d1 to turn it on for the drives and that boosts to 41Mbs on the drives, but the pdc still shows the following: PDC20265 Chipset. --- General Status - Burst Mode : enabled Host Mode: Normal Bus Clocking : 33 PCI Internal IO pad select: 10 mA Status Polling Period: 0 Interrupt Check Status Polling Delay : 0 --- Primary Channel Secondary Channel - enabled enabled 66 Clocking disabled disabled Mode PCI Mode PCI FIFO Empty FIFO Empty --- drive0 - drive1 drive0 -- drive1 -- DMA enabled:no no nono DMA Mode: NOTSET NOTSET NOTSETNOTSET PIO Mode: NOTSETNOTSET NOTSETNOTSET ... I also have the kernel config you mentioned ... also even if the hdparm works, having auto-activation on boot is really the ideal.
