PROM socketing

[SurfBoy]

so if i had a modded PROM on my HDVR2, what's the best software configuration for extracting, burning, and tivoweb?

You can just follow Stan's how-to on setting up with a prom mod. Basically, you do it just like the series 1. Kill the initrd, add the files you want, stir and enjoy.

does the prom hack "PROM Protection v1.0 by Taran" work for dvr40?
is there anything else i need to know? ie: what is flashing the chip?
so will i be able to get the bash prompt from an ethernet connection?
im using mac osx hoping that the terminal app will work. i am able to mount the drive using ext2fs (after rebooting the mac) from an external firewire case.

I'm not sure about the dvr's. But imagine it should work. I didn't use Taran's thingy. I just modded the bin file and reprogramed. (just make a back-up of the HD and the PROM *FIRST*. I know it sounds obvious, but many people don't and burn)

Do as Kraven says. killintrid is a must, and then add your software and hacks (rcsysinit.author, etc)

There is no known need to lock down the S2 flash as the SST37 chip is not believed to be in-circuit programmable.

I think the Trinity/"RID" boards, DVR40 included, all use a different version of the firmware from what we see on the older models. I have confirmed this to be the case on a DSR704; here is the ID information I found:

I can affirm this!

I'm curious if the "old" firmware will boot a newer DVR40. I wonder if the new firmware has some RID initialization stuff in it. Unfortunately, I don't have a DVR40 to play with.

Firmware 1.18 will not boot a DSR704 properly. It seems that they rearranged the code a bit but oddly enough they did not bother to add checks to keep the compromised 3.1u5 kernel from booting.

So does this mean that the PROM mod is not yet figured out for SD-DVR40 or it cannot be done?

[noneed]

Does anyone know where to get the tools if I want to do the mod by myself? It seems I can not find sst39vf010 chip for sale anywhere, its only listed on SST web site without offer to buy it, have to call them? Also after the mod, is it possible to use homieflash rather than using special IO programers? Id hate to pull it out each time Id want to make change.

No, you don't have to pull it each time assuming that the change you made will still boot the tivo.

Do you mean: each time you make a change to the eeprom image? In any case, homieflash will work. Personally, I ran a version of homieflash that gave the process highest priority, to prevent possible complications. But otherwise it's the same.

If somebody were to post (or make available) the complete SD-DVR40 eeprom image, I'm sure the proper patch could be found.

I understand that AMD's AM29LV010B is a direct replacement, so you mind find that easier to source.

[MudShark]

I was told, but haven't verrified, that the AMD chips aren't exactly the same. I guess read the data sheets and see.

They're different but supported.

My good friend expat started a thread about the Trinity boards over at pvrhax0r:

The patches for the 2.5 flash are included in his post.
