Upgrading 6.1 -> 6.2?

Postby Armin » Fri Aug 09, 2002 7:53 pm

Hello! I'm using QNX RTOS 6.1 for my Amiga Emulator and have now downloaded v. 6.2 and burned to a CD-ROM. But how can I upgrade an existing system? If I boot with the ROM and try to install, he wants to erase everything and install a new system. If I boot with HD and want to use Installer, there is no RTOS 6.2.

Hi

This is a tricky but can be exceptionally simple to do... just follow along the lines-

1. Backup /boot/fs/qnxbase.qfs (save it in same folder with another name say - qnxbase-6-1-A.qfs)
2. Scour the CD, copy the qnxbase.qfs present at cdrom/boot/fs/qnxbase.qfs to /boot/fs
3. Now we'll have to hunt /.boot . For that look for the 1.44MB floppy images present on CDROM for systems that can't boot from CD. mount the DMA image using (recalling off the head)-
mount -t qnx4 /fs/cd0/somewhere/DMAblah.144 /fs/floppyimg
next backup your /.altboot and /.boot
cp /.boot /61Aboot
cp /.altboot /61Aaltboot
then copy the 6.2 boot image
cp /fs/floppyimg/.boot /.boot

4. Reboot...

Don't worry. In case I made/you make a mistake, you can always fix it by booting from 6.2/6.1 CD (the F2 testing option) and do
cp /fs/hd0-qnx4/boot/61Aqnxbase.qfs /fs/hd0-qnx4/boot/qnxbase.qfs
cp /fs/hd0-qnx4/61Aboot /fs/hd0-qnx4/.boot

HTH
