Regarding the issue with X2 Lites not running a 1MB BIOS....
As I understand it, the jumper has to work a specific way, either enable an upper or lower BIOS, but it cannot enable BOTH BIOSes at the same time in a 1MB space. This is because the RC4 will change and will not work. Because the X2 Lites are simplified with a simple, single jumper, you can only have two options, see the upper or the lower half of the flash at bootup.
This is why an X2 Pro has the option of seeing any one of four banks, any two 512k banks, or a 1MB bank, seven possible combinations, and the eigth is disabling the chip.
That said, it should have been known that the X2 Lite (as Xeero rightfully pointed out), that the new 1MB BIOS would not work when flashed to the Lites...
Still, in the ABSENCE of a 1MB BIOS to test, who knew? Until now, the whole thing was just theory.
...but it leads to an interesting question. In the absence of a 2MB BIOS, how does anybody know if a modchip like the X-Bit will actually work for a 2MB BIOS? Will any 2MB BIOS actually work?
Ubergeek, you guys could probably make a BIOS to test this out, and it's clear the X3 will have 2MB or even more memory on board now... will there be a 2MB bank mode? Has it been tested to see if it will work? Is the size of the BIOS copied out of the LPC and allocated in protected memory determined by the boot loader?
