Tsop Flashing Not In The Xbox Options

[flexxo]

Hello guys, this is my second topic, you may know, I'm russian, and only studying English, so forgive me for the grammar.
So let's begin our story: I have an 1.6b version xbox and I know that it is impossible to flash it.
But, I think, that maybe if I can unsolder TSOP from the board, I can flash it then solder back to board.
So I have a few questions:
1) It is write protected only in the box or what?
2) If it is, what is it's clones?
3) What bios can I flash to it?
I think that's all. I have a programmer for that chips, so I think I can reflash it easily.
If someone goin' to stop me, you're always welcome.

There IS no tsop chip on the 1.6..
its not there.. does not exist.. cannot be removed.. attached.. flashed... broken.. licked.. because it is not there..

but where's the BIOS stored then?

Somewhere in the xyclops IC. Is it flashable? Probably not, but if it is, no one has shared how.

its read only,
on 1.0-1.5 xboxes the tsop is eeprom flashable because it is "Electrically Erasable Programmable Read Only Memory" stored on the Tsop "Thin Small Outline Package" (so its technically an eeprom tsop)
Obviously there is also a chip that we call the eeprom. This is on all versions. And that stores the drive info.
so where as the eeprom is known as the eeprom. the tsop is also a eeprom but because its on a tsop chip we call it a tsop.

the 1.6 does have an eeprom which obviously is re writable due to it being Electrically Erasable Programmable Read Only Memory which also stores drive data, but the 1.6 does not have a Tsop chip that holds the bios.
the bios is instead stored on a diferent chip. which is Not an eeprom compliant chip, so its read only..
because its not erasable you cant flash it.

should have answerd your question.
