Type
The payload is reset via the SYSRESET* input
signal of the I/O Controller Hub (ICH). This reset
results in a PCI reset, and thus the entire
memory region is tested and the lower 8 MB of
RAM is initialized. References to a cold reset
imply a hard reset.
The payload is reset via the RCIN* input signal
to the ICH. The ICH then maps this onto the
INIT signal to the FW-Hub and CPUs and is
asserted for 16 PCI clocks. A PCI reset is not
generated in this scenario and the contents of
the lower 8MB of RAM is maintained. References
to a warm reset imply a soft reset.
