corona2222 Posted March 30, 2022 Report Share Posted March 30, 2022 I got an og xbox with a toggle switch on the side, one wire to ground and other wire goes under the board near the lpc, I assume it decides whether to boot modchip or embedded bios, can someone confirm? thanks Quote Link to comment Share on other sites More sharing options...
OGXbox Admin Posted March 30, 2022 Report Share Posted March 30, 2022 That is a d0 wire which when grounded does tell the MCPx whether to boot from the onboard bios (TSOP) or from lpc... which is where that mod chip is attached. 1 Quote Link to comment Share on other sites More sharing options...
Mu. Posted March 30, 2022 Report Share Posted March 30, 2022 Must be a very old chip installed in that thing if it uses a dedicated switch for that purpose. Any idea which one it has? Quote Link to comment Share on other sites More sharing options...
