Re: software installation with 1 disk drive.
1) DEC has a similar problem with RC25 based Microvax-II systems,
the disk had a 25Mb fixed section, and a 25Mb removable section,
but they shared a common spindle. To load a removable disk, you
had to spin down the system disk as well. They fixed the problem
by teaching VMS to understand extended absence of the system disk.
It essentially just tapped its feet and waited for you to give it
the disk back.
2) Since the NeXT has 8Mb of main memory, it is probably practical to
have a disk copy/installation utility which pages all nonessential
code out, lock itself in memory, and then performs the copy using
all spare memory as a buffer. Agreed, this would really suck for
copying a full disk, but the average installation could probably be
done in 1-3 passes.
Opinions: ?
