Xbox 1.1 Tsop Flash, What bios to use? Options

[j0rpi]

Hello everyone. Finally got my hands on an old Xbox, and this time it was an 1.1 - Got it softmodded yesterday, but i want to be able to have a custom boot look, so i found out TSOP was preety easy. I'm gonna bridge the points later tonight, but before i do, what do i have to do? Remember my Xbox is softmodded, so i shouldn't have to deal with savegame hacks or linux (right?) My Xbox does not have a Winbond chip, it has some ST chip (as far as i could see on the chip just above to the right of the LPC)

1. Can i flash through EvoX? If so, what should i get?
2. What is the best and recommended bios to use? Remember i want to customize the boot sequence.
3. Since it's a 1.1, i need a 1MB bios right?

All help is appreciated, i know i have should have searched, and i did. No tutorials really say what bios to use, or what to use (Not in a easy way atleast...) to flash the onboard chip.

Oh, another question. Since the Xbox is softmodded, do i have to reformat the disk after TSOP flash? Considering softmod has 'hacked' files?
