I have three short but not simple questions for you AUX wizards out there: 1. Several months ago someone in this group suggested the idea of running AUX partially from the CD ROM and partially from disk, with the goal of minimizing the amount of disk spaced used for AUX. Can this be done? Has anyone tried it? 2. Others in this forum have said that Apple's 8/24 GC graphics accellerator will not work with AUX 2.0. Does this mean that the card is totally inaccessible from AUX? Or can it still be used without the accellerator capability? Does anyone at Apple know when we might see this accellerator working under AUX? 3. I have heard that unlike AUX 1.1.1, AUX 2.0 unix applications that use the toolbox must use Mac OS memory management (i.e. handles in a fixed 8 meg heap) instead of unix memory management. Is this true? Thanks in advance for your help. Russell Greenlee U S WEST Advanced Technologies russell@uswest.com

Can >this be done? Has anyone tried it? No problem. The CD-ROM is mountable as a standard file system, so anything not needed to boot (before the ROM gets mounted) can live on it. In particular, man pages, games, libraries, etc. Just mount it, and make whatever links are appropriate. Don't forget, this sucker is s-l-o-w.

That's an understatement. It's not quite as bad as running UNIX off of a boot tape :-), but it'll probably be worth it only if you're broke or don't use the files on the CD-ROM very often. -- Amanda Walker, InterCon Systems Corporation -- "Y'know, you can't have, like, a light, without a dark to stick it in...

However, since the accellerator "knows" what the internal structure of MacOS memory looks like, it can't be used with A/UX in accellerated mode. A/UX kernel memory bears little relation to that of MacOS. When this will be "fixed" is unclear (to me). > >3.

Is this true? Well, yes and no. This is true for those chunks of memory that you hand to the Toolbox (either directly or indirecly). For memory areas that the Toolbox never has to touch, stack or malloc() allocation works jes' fine. The heap is not a fixed size, but is configurable up to 16 MB (necessary to avoid the inevitable 32-bit uncleanliness (:-}). The default is your physical memory size. >Thanks in advance for your help. > > >Russell Greenlee >U S WEST Advanced Technologies >russell@uswest.com Regards, Justin Justin C.
