I have A/UX 2.0 on partition s0, swap on s1, a few user systems on s2, s3, and s4, and A/UX 1.1 on s5. How do I boot A/UX 1.1 on s5? This is what I do: I run A/UX startup, click cancel to get me a # prompt, type in pname -a to recognize partition s5 (cos it's in /etc/ptab), change (default)/ in the preferences to (0,0,5)/. Then boot. The right kernel gets booted but then I get a panic "can't mount root". I can't think of what to try next. Any ideas? The panic comes just after the message about I/O acceleration so the device drivers have been initted OK. Thanks, Tony Cooper tony@popserver.stanford.edu

Try changing the cluster number on the A/UX 1.1 partition and then booting that changed cluster. A/UX 1.1 won't be able to understand that A/UX 2.0 partition because 1.1 doesn't support the 4.2 filesystems, which is probably why it died trying to understand the partition marked in the partition map as the root partition for the default cluster. I bet the A/UX support people were very depressed by your message - it won't be fun supporting the old system and new system at different sites, but someone who wants to mix them on the same disk... groan! -- William Roberts ARPA: liam@cs.qmw.ac.uk Queen Mary & Westfield College UUCP: liam@qmw-cs.UUCP Mile End Road AppleLink: UK0087 LONDON, E1 4NS, UK Tel: 071-975 5250 (Fax: 081-980 6533)
