When I read it, I got the impression he was saying the DRAM was going crazy while a DMA transfer to the hard-drive was still going on. That doesn't require the CPU to be functional when the DRAM is corrupt, only the DMA controller. I can't personally say if that makes it any more likely though.
- codewiz 9y agoThat's right, but all stateful ICs on the motherboard have a reset pin, including the north and south bridges when they were still separate packages. Even PCI cards will receive the reset signal simultaneously. Not sure what the hard drive would do with a truncated ATA command though.
