One 3 old PCs I get the same thing: booting with the
6.2.1 CD prints …D
I’m not at the site currently, so will check, but is
the D a clue that DMA is not working ?
OR is it D for bad disk?
Something else?
thanks

‘D’ from the loader indicates that the BIOS INT13 failed reading
a disk block. This could be due to I/O error (it may possibly
be also due to the older machines not supported newer INT13X,
although I thought a CD boot used the floppy loader, which won’t
try to use this extension?). Does the same CD sucessfully boot
other/newer machines? Do the older machines boot from floppy?

Hi John,
‘D’ from the loader indicates that the BIOS INT13 failed reading
a disk block.
kabe summarized it in qdn.public.sysadmin because it’s good stuff to be in Sysadmin Guide.
This could be due to I/O error (it may possibly
be also due to the older machines not supported newer INT13X,
although I thought a CD boot used the floppy loader, which won’t
try to use this extension?).
Question mark? LOL. I have no newest 6.2.1 image yet, but old 6.2.1 image (appeared in first few
days) uses ipl-diskpc2-flop. (Just checked it out, F3(view)+F7(search)) So, it’s highly unlike the
BIOS doesn’t support function 0x2 (read sector). The problem also could be in how those machines
emulate booting from floppy when booting from CD. Do the older machines boot from other bootable CD?
Eduard.
Does the same CD sucessfully boot
other/newer machines? Do the older machines boot from floppy?

This CD works just fine on my 233 MHz Toshiba, and has worked
on various other machines as well.
These older machines boot the QNX4 install CD just fine,
so QNX4 can be installed without problem.
I’m also unable to upgrade from 6.2.0 to 6.2.1 on the one PC
that has 6.2.0 installed already, as the QNX installer “hangs”
(runs READY for ever).
I will try the “Press ESC” route anyway when I’m at the site again.
