A simple question on memory limits under 4.1bsd. We recently decided to upgrade from 4 to 8 Meg. (16K chips, 256K boards, MS-780C controllers, running interleaved). However when 4.1 boots and finds the whole 8 Meg successfully we get the following message panic: sys pt to small By pulling one board out of each card cage, we've been able to get the system up. This problem must have been known, because several people have said they've HEARD rumors to that affect, but none of them seem to know for sure. As a side note, I brought up 4.2 no problem. Any one have any ideas? Or even a good guess? Oh yeah, I know, I know, we ought to be running 4.2. Heck we even run 2.9 news so there. *** REAL SOON NOW *** we'll go to 4.2, news 2.10.2 and all sorts of nice things as soon as we fix a few things broken under 4.2 (like the fact that our modems don't work). It will be nice to be able to use our 3 new Eagles. -- Address: William P. Malloy, ITT Telecom, B & CC Engineering Group, Raleigh NC {ihnp4!mcnc, burl, ncsu, decvax!ittvax}!ittral!malloy

Just recompile with SYSPTSIZE (it's a #define) set bigger. SYSPTSIZE controls the size of ``kernelmap'', as I recall. There's a comment near its definition that says it ought to be determined at boot, based on how much memory you've got. The comment is right, as you've found out the hard way. -- (This mind accidently left blank.)
