Simple ? Question, where is my memory


Ok, so my PC has a 256MB stick of memory in it but Redboot reports
RAM: 0x00100000-0x040f0000, [0x0018dad0-0x01000000] available

What does this mean?

Looks like two ranges that overlap, one is 1MB - 64MB (approximately) and the other is 1.5ish MB through 256MB.

I'm using Grub so I select Load High on my target and it loads into 2.5MB like so:
RedBoot> load webs
Using default protocol (TFTP)
Entry point: 0x00208000, address range: 0x00208000-0x002454e0
RedBoot>


seems to be a bit past 2MB through abit past 2.25MB.

Where is the PCI memory mapped? Up near 4GB? Down in the 1MB range? Is 0-1MB verboten?

The monitor can look out in that space but if there was a clear explanation of what those numbers meant it would be helpful. Pointer?
