I'm new in this, and i'm reading the source and i have a question, which one
it's exactly the first instruction that the processor execute when the pc is
booting?, in which file is it?
Here's a little summary I wrote a while ago.. don't know if it is still
correct and complete.
I don't complete understand the relationship
between a normal bios and the
kernel, i think that the bios it's has to pass some data to the kernel, if
that's true ¿how exactly is that data passed to the kernel?
There are several possibilities. Either the information is placed at
well known addresses or in a certain address range, using a signature so
the kernel can find it.
Or the Kernel does callbacks (intXX).
In linuxbios, how it's this issue handle?
LinuxBIOS provides tables: ACPI, MPTABLE, PIRQ table, and a LinuxBIOS
table which should some day obsolete all the other tables.
No callbacks. They are considered unsafe and error prone.
