Booting or rebooting using a partition bootloader

If you boot or reboot and use a partition bootloader from QNX Neutrino on a QNX4 partition, an error will occur.

Because a driver sees the disk differently from when it was initialized, the secondary boot loader won't be looking for the root block, or subsequent blocks, in the correct place.

You'll see a message similar to this:

Press ESC for .altboot......

followed by a letter or character:

When these characters appear, the boot process halts.
