Well, not LinuxBIOS, but yes, from a custom BIOS. With things like the SMI
interrupt one could potentially get at a pretty wedged system from a BIOS.
Another factor to consider, (pardon my unfamiliarity with Linux and its
VM system), is that it looks like a single virtual memory address is associated
with each page in the dump file. It doesn't seem like one could easily access
all user pages, because pages from different tasks would have the same address.
Is this address somehow unique in the mem_map table?
