Title: G4 yikes! (PCI) with G3 ROM
Post by: idiotoflinux on November 20, 2016, 01:25:07 PM
Hi,

I wanted the option-menu on my Yikes!-G4 and read the mainboard waas largely the same.

long story short, i just flashed (with some help of ResEdit) the B&W G3 Bootrom on my Yikes! G4 and just found out of the G4 lockout of the B&W rom :o...

is there a way to force a flash (i.e. emergency flash or JTAG/SPI or something)?

or do i need a G3 CPU?....
