Yes, that's possible. Drop the loader to the prompt and do the following:It would be nice if I can set hw.ata.ata_dma="0" at the loader prompt during bootup, so that the system at least will boot from harddisk. Is that possible?
set hw.ata.ata_dma=0
boot
btw: I have a similar problems, but not with the boot disc, but one of my data drives, thus I want ata_dma enabled for the other discs.
I have to dispatch a
atacontrol mode 1 foo UDMA33
to set this drive (slave on second controller) to UDMA33 (otherwise it
would use UDMA100). But I have to do it before /etc/rc.d/fsck starts
accessing the device. Right now I've added above line to the beginning
of aforesaid script.
Is there a nicer/better place to tell the kernel (don't like editing the
rc-scripts).
You can use /etc/rc.early for that. You'll have to create it if it doesn't yet exist. Put 'atacontrol mode 1 foo UDMA33' in it, and it should execute that command before mounting the drives.
Note that you can put this in loader.conf as well - if you're having trouble booting the system to do it, boot to "safe mode" - should get you in.
I have an old Aladdin V with a buggy UDMA chipset, and doing this fixed the problem rather nicely.
