Just confirmed that the above photo method does work. A 10k resistor shorting the two pins of the flash chip will enable boot mode. The resistor must stay in place during the entire process.

The easiest way is to probably wire a switch and a 10k resistor and solder it in place for future use.

can someone explain to me why we use pin 24(QD4 listed as a input/output) and 32(ground) with a resistor on that chip to boot mode it rather than the 44(RESET#) pin

data sheet for AM29F800BB-70SI

page 5 has pinout
page 8 has information on reset.

Resetting the flash chip has nothing to do with bootmode.
