Memory Hole on 2.4
I want to upgrade from 2.2.16 to 2.4. I have Compaq Prosignia 300 with a memory hole, which cannot be turned off. There was no problem with that on 2.2.16, I just put "mem=64M" to kernel as a boot option. It does not appear to be functional on 2.4, I only finds 15MB. I use the same LILO v.21, rh6.2.

Well this is unrelated to your problem, but as a side-note: if you are planning on using 2.4 going forward, you may need to upgrade some of your OS-related tools like modutils, binutils, e2fsprogs, et al. Look in Documentation/Changes.
Again, this has nothing to do with your current memory hole issues, but it is something to consider if you solve your memory hole issues.
I seem to remember being able to map out ranges of memory either as parameters to the kernel.. or by editing a source file--so that if you know the linear address of the memory range you want to omit, you can do so. Actually I think to do this you may need to modify one of the kernel source files. If you are willing to do this write me back and I will try hard and remember which file you have to modify...
