Title Error: "Press ESC for alternate OS.... C" message
Ref. No. QNX.000005861
Category(ies) Installation, Filesystem
Issue We tried to boot and got the message:
Press ESC for alternate OS.... C

Solution The 'C' in that message means that the partition is not under 1023 cylinders.

Make sure that LBA mode is enabled in the BIOS, and that QNX in installed in the lower 1024 cylinders.
