K1297-G20 Protocol Tester

Hello, I have 2 Tektronix K1297-G20 protocol testers that I want to use to monitor the A and Abis interface in our lab. The problem is that the battery that was keeping the boot parameters of the AP-4 boards has discharged, and the boards are not booting (the boot command line is lost, I have only garbage). Does anyone have access to a functional system to retrieve the boot parameters or does anyone know the right values for the boot command line? Thank you, Dan.
