A 233 Mhz here doesn’t want to boot without disabling
DMA. How can one disable this permanently so I don’t have
to press Esc every time?
Thanks

There should be ‘non-DMA’ item in the boot menu. Make it default.

Esc works? from the DOS filesystem - DOS boot config menu?


I assumed boot floppy or partition

mount (if) floppy - mount -t qnx4 /dev/fd0 /fs/fd0-qnx4
swap .altboot & .boot - cd /fs/fd0-qnx4
cp .boot .temp; cp .altboot .boot; cp .temp .altboot
rm .temp

Thanks-swapped .boot .altboot in /
(RTP has its own partition)

(Sometimes I expect things to be totally different compared
to QNX4, when in fact somethings are identical)

Thanks for the clue.
