Subject: Prometheus/Othello installs VMEM too small': can hit bad spots (cf AR#379)

Lisp Version: 

Description: '
The InstallLispTool has been fixed to install Interlisp-D virtual memory larger than the size of the sysout tool. However, it is still the case that the Installation Utility (which is Prometheus+script) uses the old style of installation. This is serious because the virtual memory is not allocated in a way that avoids bad pages, which can lead to serious problems running Interlisp on disks with bad spots.'

If you need the sources for prometheus, they are obtainable. I had copies of them all at one time and can get them again.'
'
The reason why enhancing prometheus is still a good idea is that people still load sysouts directly onto their lisp volumes using prometheus.'
'
Cutting that off as a possibility would make using Interlisp-D on an 1108 less convenient in those instances (e.g., setting up for a demo with a disk, you can now just configure the disk, install lisp and go; you don''t have to go thru the step of installing the InstallLispTool before installing the sysout.)'
