    PROM Mod for Tivo HD XL

    I just socketed my new Tivo HD XL to start hacking away. I was looking for a PROM mod for it and haven't been able to find the mod for PROM version 1.06 ("CBOM-00014-000 V1.06" on the chip, "TiVo/mips/Gen06/rel.v1.06-rel_C1" in the PROM). Does a PROM mod exist for that version? If so, could someone direct me where to look for it? If not, I can send the PROM if someone knows where to look for the change(s).

    Thanks in advance!

    Do a dump of the prom and post the file here. Part of the problem is that not many able to hack their system would spend the extra money on an XL.

    Why not try prom version 1.05 and see if it works?

    I'll try the older PROM and bit later and let you know if it works. In the mean time, here's the 1.06 PROM.

    Code:
    0x3DF8 - change 04400012 to 00000000
    0x8664 - beginning of gzip image
    0x2c98 - change 1043000a to 1000000a (offset from within gzip image)
    untested, yada, yada, yada
