Looking for very old Katana 752i boot code.

[Steven J. Hill]

Recently got a hold of a Katana 752i board. I was able to dump the boot 
memory and it shows up as:

    PPCBoot 1.2.0 (May 30 2006 - 12:54:57)1.5s

In the Katana 752i user manual however, it shows console output as:

    PPCBoot 1.2.0 (Oct 31 2007 - 12:52:52)1.7s
    CPU:   750GX v1.2 @ 900 MHz
    Board: Katana752i
    BusHz: 200000000
    I2C:   ready
    DRAM:  512MB DDR SDRAM in slot 0 VM485L6523C-CC Early setup ECC 
(Clearing..)
           512 MB Reserving 32MB for EDNR at 0x1e000000
    FLASH: [512kB at f8000000] [32MB at e8000000] [32MB at ea000000] 64.5 MB
    cPCI:  Enabled Remap Addr: 0x80000000 Window: 0x1000000
    PCI:   Bus Host
    Waiting For EREADY ('q' to exit w/o enum).
    [...]

The board is running a PPCBoot image that is 1.5 years behind what the 
manual has. *sigh* There are no fault lights and there are link lights for 
the Ethernet ports, but no serial console output. My BDI2000 shows it stuck 
in a loop waiting for something. In the user guide, Emerson says the code 
is GPL, but none of their Internet domains work anymore. Any chance someone 
has a copy of the PPCBoot that ran on their hardware? Older versions of the 
Linux kernel supported this board. I have been going through U-Boot git, 
but am having no success in finding code. Any help appreciated. Thanks.
