Greetings again!
Running XeniumOS 2.3.1, but it turns out no bios are present. I've done some research, but the information is scattered from over 15 years and there are a lot of different opinions on the matter. 
What are the present day recommended bios for open xenium running xenium 2.3.1? Are there any bios/dashboard packages or bundles available? Thanks!

Greetings!
I am very new to the OG XBOX (both the console and the forums).
I have a 1.4v xbox that I have dusted off recently to install Open Xenium chip. The console was a bit dirty, so I gave it a good cleaning, removed the clock capacitor (which had just started to leak), replaced the fan with a Nexus, and installed the new open Xenium chip. 
The system seems to be running great and immediately boots into the Xenium OS screen when powered on. The problem: no controller inputs are recognized in any of the controller ports (I've tried with four different working controllers). So basically I boot to Xenium OS, but cannot select any of the menu options. (I should also mention that before the Xenium install, everything had been working fine).
Now, when this first happened, naturally my thought was that I had not properly reconnected the ports back to the motherboard, but upon checking they seemed to be well connected (I cleaned the ports and reconnected for good measure). I have looked at the traces on the motherboard and they seem fine. I imagine the chip install went okay since I can boot into Xenium OS(?) Port have been cleaned thoroughly. The only thing I have not tried is swapping the 1&2 ports with the 3&4 ports (in case there is a problem with port #1, and Xenium OS will only recognize input from Port #1???)
Does anyone have any idea what the problem may be? It seems odd that none of the 4 controller ports are working, and all I am left with is an idle Xenium OS screen on my system. Could it be a single bad solder joint on the Xenium chip?Could it be that Port #1 is busted?
Thanks for the help!

is there an alternate place to solder the d0 port than the chip ? im trying to do a hotswap to reflash my other chip
