How much RAM is on this system?
Comment 2 jzeman 2002-11-01 11:42:29 EST
48 MB
Comment 3 Michael Fulbright 2002-11-01 12:59:20 EST
Could you try booting with 'mem=40M' on the command line.

I think you are on the border of having enough RAM to run the install w/o
enabling swap, so reducing the RAM the kernel thinks your machine has will force
it to use swap and perhaps suceed.

This appears to be a duplicate of Bug 76123.  The problem is that there is not
enough memory to process the transactions that are to be executed by the
installer.  Anaconda, in GUI mode, requires at least 64M+ of memory and 128M of

You can alternatively attempt to install Red Hat Linux 8.0 in text mode by
specifying "linux text" at the SYSLINUX prompt upon first boot.  Anaconda, in
text mode, is more lenient on memory resources.
