Any suggestions about how to do so?
man acpidump
How do you run that on a system that won't boot?
You said the system worked with 4 GB (albeit detecting only 3.5 GB).
Yes, this is correct. A number of people have explained why it only detected 3.5 GB in this configuration.
My perception of this whole ACPI thing is that it is fixed in your BIOS (although it can be overridden by the OS). As such, the amount of RAM you have in the machine shouldn't change acpidump results. Is that not correct?
This is absolutely correct.
Ah, so you meant to say that the output from the system running with 4 GB memory is useful? That wasn't in the man page you pointed to. What it does say is:
When invoked with the -t flag, the acpidump utility dumps contents of the following tables:
... MADT
This may be the case, but between man page and output some terminology must have changed. I can't see any reference to anything like an MADT there. Does that mean that there isn't one, or that ACPI can't find it, or does the section APIC refer to/dump the MADT? Here's the complete output of acpidump -t, anyway:
<snip acpidump output>
Since I don't know anything about ACPI, this doesn't say too much to me. Suggestions welcome. If the APIC section is the MADT, it looks as if we should update the docco.
My limited research (as in, Google) shows that the MADT was defined as part of ACPI 2.0:

According to your previous link the motherboard specs, it supports both ACPI 1.0A and 2.0. Perhaps there is a BIOS knob to toggle between the two?
