I think it is impossble to do in SRM.

In AlphaBIOS with X86 emulation enabled it COULD be possible
to run such PCI SATA card with its own BIOS, so it will intercept.
But I do not know what is the state of booting of Linux using AlphaBIOS
at all. aboot and MILO do not support it AFAIK, and AFAIK there is no grub port.

So, by running I was saying that I will boot using other means
(build-in or other supported SCSI or built-in IDE, network using BOOTP+TFTP),
and then use PCI SATA controler using Linux drivers.

For example in one of my XP1000, i was using Promise FastTrak100 TX2,
to connect one more IDE disk (becuase XP1000 have only ONE IDE port exposed,
and it was filled with CDROM and IDE/ATA drive already). It was also
becasue I was investigating DMA problems with bulit-in IDE controler.
This card works under Linux, but I have still had some corruptions,
so I will attribute it to the DMA.
This is very misterious, and would like to investigate it further.
(Because this maybe mean i cannot use SATA controler which 
probably in all cases use DMA).
