but some of the x2 bioses work ok, and the x3
Nearly...
You can't run X3 BIOSes on a TSOP, or an any chip that isn't an X3. If you flash an X3 BIOS to a TSOP you need to fit a chip, or use a 29-wire mod, or remove the TSOP and flash it externally.

its also possible to just leave the wires connected and simply run from the 1st 256k.
...
have you tried to unground a19?
could let you boot to a situation where you can flash. or to a point where you can Soft mod then flash..
all depends on the flash configuration on the chip though
The 3-wire trick doesn't quite work like that. All wires floating (i.e. disconnected) means that all banks on the TSOP have to contain the same BIOS, because the boot code checks that, so disconnecting A19 doesn't work if the TSOP contains different BIOSes.
You have to have A18 and A19 either grounded or connected to +3.3V in order to select a specific 256k or 512k bank:
- If A19 is connected to ground then the xbox only sees half of the 1MB tsop chip which is 512kB in size
- If A19 is connected to 3.3v then the xbox only sees the other half of the 1MB chip which is 512kB in size
The example above will get you going if 2 banks is enough and would require only one switch. If you want to have 4 banks then while you have A19 connected to either ground or 3.3v and it only sees one half of the chip you have to also connect A18:
- If you connect A18 to ground the xbox will only see half of that 512kB bank which is 256kB in size
- If you connect A18 to 3.3v the xbox will only see the other half of that 512kB bank which is 256kB in size
So:
CODE
A18 Float A18 Gnd A18 3.3v
A19 Gnd 0-512 0-256 256-512
A19 3.3V 512-1024 512-768 768-1024

went through the steps of soft modding my secondary box (currently hardmodded w/ a chip) w/ the hexen disc and I got to the part where it told me that the drive was going to be formatted into the F and overflow into the G etc etc prompt
I don't recall anything in HeXEn that would give you this message, or anything similar..... Which option did you use, and what exactly did you do?

Hello, my apologies as I wasn't really exact with what the message was. More specifically it said that this option installs unleashx as the dashboard with nkpatcher.67 with all space above 8gb and below 137gb put on the f partition and the rest is on the g partition.
this was where i abandoned the softmodding process as I don't really need that xbox softmodded and certainly didn't want to have to re-populate the hdd w/ all my files again.
Brief summary of what I did was:
1. locked the hdd using evox to boot w/ chip disabled to ensure normal microsoft bios was intact.
2. booted hexen w/ chip enabled and clicked softmod xbox tools -->krayzie one-click installer-->ntsc, sc game save.
3. let that run its course, it booted into unleashx, backed up the eeprom, returned to menu, then clicked 'basic install unleashx dashboard' and this is when the above stated message was shown and where I subsequently quit the process.
Thanks for the response.
