Equipment Details:
Xbox 1.2 (5101 MS Bios)
Samsung DVD
OEM Seagate HDD
New Stuff:
Xecuter 2.2 Lite
Older unknown but previously successfully used Bios Load CD
IBM 120GB HDD.
When following 2.2 visual instructions for pin header install, all solder points perfect. d0 point as shown did not work (bottom of board) so I used the top location. Xecuter booted and flashed BIOS. Once flashed, replaced HDD and have not booted past error screen since. Depending on switch config (Enable / disable, Protect / unprotect, bank 1/2) I get one of the following error codes: 05, 16, 21. Most common is 16 (05 was w/ change on HDD jumpers actually). Have tried a couple different EvoX boot config CDs on CDRW media. In some cases the Xecuter error screen is diagonally split but error code is still visible. Tried original HD and errors still occur, also tested a 120GB WD HDD, no change. Disconnected the Xecuter chip (leaving d0 and ground attached, but not plugged in, and system then goes to 21 error code.
If anyone has any ideas it would be nice. TIA
