Description Gabor Kaszas 2000-10-10 06:34:18 UTC
In my IBM ThinkPad 600 there is 228 MB amount of memory.
RedHat have found only 64MB of them.

Comment 1 Alan Cox 2000-10-10 14:33:23 UTC
This is a BIOS problem. The machine doesn't correctly support E801 memory
sizing. You can pass
mem=228M as a lilo option, or add


to the lilo.conf for the kernel. Be sure to try this on the command line first
before adding it to the
lilo configuration. You may need to give 227M on some systems as some ram gets
borrowed by
the BIOS at times.

The 2.4test tree also tries to use 0xE820 memory sizing which tends to be less
buggy (vendors have to get it right as windows 9x uses E820 sizing 8))
