For complex reasons, I needed to take 8Mb of ram (one memory card) out of an RS/6000 model 320. Now that it has only 8Mb of ram left, it won't boot. It gives error 949 on the red 3-digit display (means direct-attached disk isn't responding, or some other seemingly irrelevant problem). Is there anything I can do to avoid reinstalling AIX? -- Matt Emerson matt@karazm.math.uh.edu

A special version of the kernel is built on 8MB systems, which uses somewhat less memory. This kernel will also run with more memory, but not the other way around. My first computer had 2000 6-bit words. Doesn't seem THAT long ago. Anyone want to place bets on when the first operating system which won't boot in 1GB RAM will be shipped? -- Bob Shair shair@chgvmic1.vnet.ibm.com Scientific Computing Specialist SHAIR@UIUCVMD (bitnet) IBM Champaign

If you can temporarily get back that 8MB card to get back to 16MB, then you won't need to boot in maintenance mode; otherwise, you will. After you've booted your machine, (after running /etc/continue if in maintenance mode), edit /usr/bin/bosboot. Look for a comment which will say something like "If there is only 8MB of memory, must compress the RAM disk". Comment out the "if [ "$sizemem" -le 8192 ]" the "then" that follows, then the "fi" which follows that. Write the file back to disk. sync if you are in maintenance mode. Then, run bosboot -a. You should then have a system which will boot in 8MB. -- Marc Stephenson IBM PSPA (Personal System Programming - Austin,TX) DISCLAIMER: The content of this posting is independent of official IBM position. marc@stingray.austin.ibm.com VNET: MARC at AUSVMQ IBM T/L: 793-3796
