HuH? I you enable "DMA if available" under the primary or secondary IDE channels in IDE ATA/ATAPI controllers under device manager, what happens? If the device is capable of DMA or UDMA modes, that will be detected and selected. What type of device are you referring to? What is listed in Current Transfer Mode?

OP
The chipset is Sis 5513.
It suppoerts DMA/UDMA/ATA33/WHATEVER
The HDD is a Quantum Fireball 6.4 EX ATA33
Linux supports udma with this setup (12.55mb/sec)
Win9x supports udma with this setup (10mb/sec)
 
your missing the [point], i want to disable the startup check because it selects PIO (2.5mb/sec) over udma ;which is slow and crap
 
any suggestions??????????

I would not recommmend overriding that setting - if the drivers don't support udma or dma then they don't support udma. If you have selected DMA if available, then if it is not selected you will hose your system otherwise. This isn't like the little checkmark in Win9x where you can override the setting. Check with SIS for newer drivers.
