HOW & WHEN do you select the bios you want to run?




I first buggered my x2.1 with the 1st 4978, so i don't want to be beaten by this, i wanna find out what the cool stuff does!!

heinrich,

Isn't X4977 a 256k BIOS?  So couldn't you put that in bank 1, maybe cromwell in ban2, then 4978.03 in 3 and 4?


Thanks!

The X2.2 Lite can only boot from 2 memory banks.  In fact, if you have two different 256k BIOS'es on either half of the chip, the X2 Lite will ALWAYS boot from the BIOS on 2nd half of the memory bank, that's just how the chip was designed.  Heinrich's example is correct, load x2_4977 on one bank (you'll need two of them on the same bank so that they add up to 512k), and load the 512k x2_4978.03 BIOS onto the other bank.    

An X2 Pro would allow you to run a setup like the one you mention above, where you can boot 3 distinct BIOS'es.

The "1.0/1.1" jumper switches BIOS banks.

I have set the following in the BIOS MANAGER.  I have an Xecuter 2.2 PRO.

Bank1 : xecuter_flashbios.bin
Bank2 : x2_4977.bin
Bank3 : x2_4978.03_1mb(ORIGINAL).bin
MultiPort 1
Bank4 : x2_4978.03_1mb(ORIGNAL).bin
Multipart : 2

I then save this as bios.bin.  

The flash always stops at approximately 1/4.  The bar never finishes.  I have tried it in FlashBIOS, and also now in EVOX, and both do the exact same thing.   Anyone have any idea why this would happen?

After you turn the xbox, but before you flash, turn the chip off, and put dips 1-3 in the down position (off).
