Good day,
Thanks for your reply.
I had incorrectly given the syntax that I had used, sorry. I _did_ use
append="mem=800M".
Also, grub doesn't appear to be appending anything to the line (although I
have read both documentation and bug reports on that) EVEN if I use the
append and/or uppermem options. The splash screen always reports 1GB of
RAM, BTW. Log has:
Jan 23 09:37:26 ks kernel: Kernel command line: ro root=/dev/rd/c0d0p1
If this helps, here is the "original" grub.conf. Things I have tried
include:
- append="mem=800M" to the global options, boot options, and both.
- uppermem=819200 to the global options, boot options, and both.
- Both append and uppermem together.
- Adding "mem=800M" to the end of the command manually.
Also, here is what the log shows LILO as using (which is working)...
Jan 23 09:47:57 ks kernel: Kernel command line: auto BOOT_IMAGE=linux ro
root=3001 BOOT_FILE=/boot/vmlinuz-2.4.9-13enterprise mem=800M

this is wrong, it should be:
append="mem=800M"
but for grub its different, that syntax is for lilo.
in grub.conf
kernel /vmlinuz root=/dev/hda1 ro mem=800M
also grub appends a mem= line automatically, so you may need to rebuild
the package with the configure option to disable this.
