Hmmm, I didn't notice that there is a BIOS which requires
memory area below 640K even when calling INT 15H/E820.
We cannot trust that today's BOISes have INT 12H, so it's
difficult to determine base memory size w/o INT 15H/E820.
OK, some questions:
- What is the size of your base memory (reported by boot loader)?
- Does attached patches solve your problem?
- Is this problem specific to IBM Netvista?
Thanks
