It boots now - great!
What limitations exist with .alt OS image?
It forces devb-eide not to use dma modes, i.e. system will use PIO mode for
disk operations. It’s slowly and require CPU intervension for
reading/writing hard disk, but it should reliable work. You should decide if
it answers your requirements. I’m unaware of another limitations.
Can I configure QNX 6.2 to boot .alt OS image automatically?
Yeah, just swap /.boot and /.altboot.

Try to press (fast enough) Esc key during boot up to boot .alt OS image.
Alternative image should not use UDMA EIDE mode. Seems you have problems
with EIDE controller and UDMA mode, or QNX doesn’t properly support
QNX 6.1 probably was unable to force UDMA mode on your hardware, that’s
it worked >

I now completely removed EVERYTHING from my harddisk, configured two
partitions with partitionmagic and installed QNX 6.2 NC from the CD on
first (bootable) harddisk partition. That should be the cleanest
How’s the diagnostics from verbose boot? (Space-F6 during boot)
I can’t write so fast as I read the errors (is there a possibility to
the errors?), it often states ASC_MEDIA_NOT_PRESENT and also UDMA CRC
I have tried to find the UDMA settings in the BIOS, but there is no
adjustment possible (I do not even know if it would help anything).
At the end there is always:
Starting with safe mode
Remounting /fs/hd0-qnx4/boot/fs/qnxbase.qfs as /pkgs/base
Starting /proc/boot/devc-con -n4
Unable to locate fs-pkg
You still haven’t told us your machine configuration yet.
Tell what hardwares you use (everything) and how it’s connected,
in every detail. Oh, all BIOS setup should be consulted too.
1,4 GHz Athlon with K7T266 Pro motherboard (VIA VT8366 and VIA VT8233
chipset), 768 MB DDR RAM, …
what more is important?
What I don’t understand is, how come that QNX 6.1 runs properly while
6.2 doesn’t even start on the same machine with the same BIOS and
