Because EIDE scanning spends too much time, I want to detect only specific device.
I have only an eide device, i.e. 8GB ATA Flash which vid=0x8086, did=0x2850, irq=0xe.

I tried this:
[+script] startup-script = {
    ...
    [pri=10o] PATH=/proc/boot diskboot -b -D0 -odevb-eide,eide,vid=0x8086,did=0x2850,irq=0xe
    ...
}
But it does not work, still with EIDE scanning when Neutrino starts. 

How can I pass an option to devb-eide in buildfile?
