Well, for upper memory, you're okay. However, it's not safe to assume 640kB of lower memory. I have a system that only has 512kB for some reason (haven't figured out why yet.) So you'll need to test for BOTH the amount of lower AND upper memory.

My computer won't do anything but beep if I don't have memory in the banks. In the past, I've also tried with other computers. If I remember right, they all did the same. I believe that lower memory (at least in most cases) is part of the memory that you put in the banks, and not something that is soldered to the motherboard.

Which BIOS call gives back the low memory size?
Or must I check this memory directly?
bye,
