Hi
I just bought two xbit 1.5 chips and have tried to flash them with the evox 1.6 bios before installing them on a v1.6 xbox.
Initially, when i ran the software i got the 'missing comdlg32.ocx file' error which i fixed and i could then run the winxp flash software and i also found that i had to connected the chip to a USB port on the motherboard.
When i tried to format the chip, the program says 'format starting' but nothing appears to happen, i left it for 10 minutes and still no change.
i was able to select all of the partitions (i chose the 6 partition format) as if it had been formatted and the software appeared to be able to write and erase them (the 'starting format' message would change and go through the motions of the writing and erasing processes) i.e. the software hadn't crashed.
However, when i tried to varify the partitions, after i opened the bios to be verified, i got an 'error at 0x180000' message.
I then disconnected and reconnected the chip and it appeared to need formatting again.
I've tried on two computers and one laptop (all different pentium chipsets) and got exactly the same messages. i've successfully formatted and flashed an old version xbit chip with the v1.0 software on this same computer (P5 motherboard). Both of the new xbit 1.5 chips behaved in exactly the same way.
These are the assumptions i made
1) the xbit 1.5 chip can be flashed before installation to the xbox, with only the main board and USB and dipswitch board connected
2) the black and yellow cables are connected in the same way as the old version (i couldn't see any Y or B marks near the connectors on the main board of the chip)
