It probably shouldn't matter which BIOS you load onto the Chameleon, whether it's evoX or xecuter, but this is the one problem I'm having with TWO different Chameleons.
I did the pin header install, that went fine, all my voltages check out (used a nice Fluke Multimeter to test voltage levels), and I've connected up the Power and Eject PINS so that I can operate my Chameleon in Mode 4. I flipped the appropriate dip switches so that the Chameleon is in mode 4 - when I hold my eject button down (for about 3 seconds) I boot directly into the XBOX M$ dashboard, exactly as it's supposed to work.
I've been flashing BIOSes onto both Chameleon chips using the Matrix programmer attached to a PC, and it appears to work. So far, I've tried evoX D.6 (Ejectfix), x2_4977, and the Cromwell BIOS - the only one that I can get to work is the Cromwell, none of the other BIOSes appear to work. The XBOX "frags" when I try to boot to any of the memory banks that have evoX or xecuter BIOSes installed. The XBOX boots from the modchip just fine from the bank that Cromwell is installed on, and I have not yet had successes flashing a BIOS via software (using OzXFlash) from Cromwell.
At any rate, are there specific BIOSes that are known to work without problems with the Chameleon? Does the Xodus Programmer screw up non-Cromwell BIOS flashes? Can I use x2bm to flash a Chameleon?
Here's another question that I've had problems finding answers to: In order to get a BIOS onto that SECOND memory bank in mode 4, do I have to flash a BIOS in mode 1 and then flip the switches to mode 4? In mode 4, memory bank #2 is write-protected, so it's not possible to flash anything onto that bank once the dipswtiches are flipped to mode 4. OR, does the chip HAVE to be flashed in the mode you're planning on using?
Any help would be greatly appreciated. Thanks.
[edit]
Note that in the different modes, the BIOS sizes are different. Mode 1 is 4x256k, Mode 2 is 2x512k, Mode 3 is 1x1024k, and Mode 4 is 2x256k (with the second bank in write-protect), and the 3rd bank is 512k. If you flash (let's say we're gonna flash the Chameleon Cromwell onto ALL 4 256k banks in mode 1) in mode 1, then switch to Mode 4, will that jack up the entire flash since the ROM bank sizes and layouts have changed, or does that not matter?
