I used Silverlinnig to partition a 300 meg hard disk, 150 for AUX and the other 150 in 4 mac partitions. As I found out, AUX will only mount the first Mac volume wich is the startup (System & FInder), but the volumes I really need are the other three. Does anybody know how to 'fool' the system so that I can mount the other Mac volumes??? Please be specific in your answer (If there is one) Thanks.

The standard Apple partitioning scheme doesn't allow for multiple mac partitions on one scsi device - silverlining does some sort of end run around this to give you what appear to be multiple partitions but, I believe, are really just large files on the one "true" mac partition. Not surprisingly, this doesn't work with A/UX, perhaps because the Mac driver isn't used to access the disk. I may have the details wrong on this one, but that's the general idea. anders

Nowhere in the whole A/UX distribution is there a driver for multiple partitions. So you can't fool the system. Waste of time trying. I wrote a program to mount multiple partitions. But everytime I go to release it I think up a new feature to add to it. My problem is that it's the first real Mac program I have written (I always cheated and used Prorotyper) but this is system software from scratch. Everytime I read a new chapter in IM I find something new to try out. That's Apple's fault. They should have given us MSDOS. Tony Cooper

The SCSI partitioning scheme allows for multiple Mac partitions, just like it allows for multiple 'usr' partitions (and multiple 'free' partitions). Its just that the driver has to be able to handle it. In the MacOS environment, it seems that just about everyone except Apple has figured out how to handle multiple HFS partitions (e.g. SuperMac, Micronet, LaCie,...). Under A/UX, you are stuck (at least for the time being) with Apple's inability (or unwillingness) to write such a driver. Marc Kaufman (kaufman@Neon.stanford.edu)

This is because slice 1 is usually a Swap partition. I don't _think_ you're actually risking anything here, but I wouldn't chance it. The MacOS startup shell is badly broken in this respect, and I don't trust it not to do funny things to any slice 1 it happens to meet. --- Alexis Rosen Owner/Sysadmin, PANIX Public Access Unix, NY {cmcl2,apple}!panix!alexis ps- I'm off to Europe for three weeks.
