OS developing, what memory can I us(where is RAM)?

OS developing, what memory can I us(where is RAM)?

OS developing, what memory can I us(where is RAM)?

(OP)
I'm interesting in developing an very small, simple real mode Operating System of my own. I want to load the kernel to some point in the memory, I don't know what point.
For example, memory in 0000:0000 is taken by the interrupt vector table, another is taken by BIOS. Where can I put my kernel?
Please help me.
You can send your answers to alexanderprog@yahoo.com as well.

Maybe you can get suggestion from linux source code!

Hello,

The memory you can use starts at (these are hex addresses) 60:0 (0:600) or 70:0 (0:700). Source: Memory.lst of the Ralf Brown Interrupt List
