The bios chip has been detected! I'm so happy, it's taken me a month and a half but i'm almost there! :)
For those attempting this in the future, what worked was to connect the four signal pins to their counterparts (CS, MISO, MOSI, CLK), Ground to Ground, and also Vcc to 3V3, and disconnect the AC power and remove the laptop battery.
It's currently "Reading flash..."
I'll let you guys know how it goes, thanks so much for everything!
