It would be great if the admin could install SyntaxHighlight extension to media wiki

http://www.mediawiki.org/wiki/Extension:ASHighlight

on my list of things to do Admin 21:25, 11 April 2011 (CDT)


observations comparing dumps

Encrypted files appear to have a header: 

From metldr

From bootldr

 00FC0000  00 00 2F 4B 53 92 1C E7 F7 33 41 76 9B 7A 1E D6  ../KS’.ç÷3Av›z.Ö

also to note that these values are found within the eeid region.

Also noted that near the end of region 1 there seems to be this recurring pattern, it repeats the following 20 bytes 199 times 

00EFD740                          0A 9E F8 79 2B 99 37 5A          .žøy+™7Z
00EFD750  53 49 92 D7 A5 BD 99 2A 26 2D 39 B8              SI’×¥½™*&-9¸

then it has these 15 bytes: 

00EFE6D0              8C 37 E4 F4 CC CC 59 02 D0 FA B8 A5      Œ7äôÌÌY.Ðú¸¥
00EFE6E0  1E 42 98 DD 54 AF 8D 5E                          .B˜ÝT¯.^

Then it repeats the first 20 bytes 199 times, looks like the tried to hide it?

same on the other dump but different data 

00EFD740                          17 D8 FE B6 56 B6 84 F2          .Øþ¶V¶„ò

Done some work on decoding region 2 today:
Region 2 seems to = vflash partition table? These might be the first 2 regions?
partition table is 4096 bytes.
Format:
16 bytes 00's
16 bytes magic: 00 00 00 00 0F AC E0 FF 00 00 00 00 DE AD FA CE
8 bytes 0x03
8 bytes 0x02 (number of paritions?)
144 bytes 00's
Partition entries:
8 bytes entry point (entry point * 0x200) relative to 0x00 on flash
8 bytes entry length (entry length * 0x200)
32 bytes 10 70 00 00 01 00 00 01 00 00 00 00 00 00 00 03 10 70 00 00 02 00 00 01 00 00 00 00 00 00 00 03
96 bytes 00's

EID correctness

  [8/31/2011 1:41:13 AM] xxxxxxxxxxxxxx: the information on the PS3 dev wiki was intentionally faulty
  [8/31/2011 1:41:15 AM] qqqqq: Use the creativity or fail to find it.
[...]
  [8/31/2011 1:41:34 AM] xxxxxxxxxxxxxx: so people can't use the 'knowledge'
[...]
  [8/31/2011 1:41:43 AM] qqqqq: xxxxxx, uuuu has done a very good job at fixing what IS wrong. If you saw something wrong, why didn't you ask uuuu about it to fix it?
  [8/31/2011 1:41:55 AM] xxxxxxxxxxxxxx: that's not what guys like rrrrrrr have told me
  [8/31/2011 1:41:58 AM] xxxxxxxxxxxxxx: it's intentionally faulty
  [8/31/2011 1:42:03 AM] qqqqq: Instead you left it  how it was and bitched about it.
  [8/31/2011 1:42:07 AM] xxxxxxxxxxxxxx: to prevent any meaningful extraction of keys
  [8/31/2011 1:42:11 AM] qqqqq: If it was fault again talk to uuuu
  [8/31/2011 1:42:24 AM] xxxxxxxxxxxxxx: no - uuuu could not have even known about it
  [8/31/2011 1:42:28 AM] xxxxxxxxxxxxxx: it was something only a kkkk could know
  [8/31/2011 1:42:45 AM] qqqqq: You'd be surprised what uuuu knows. he really is a walking encyclopedia of the ps3.
  [8/31/2011 1:42:48 AM] xxxxxxxxxxxxxx: that wiki is compromised with purposeful misinformation
  [8/31/2011 1:42:59 AM] xxxxxxxxxxxxxx: and that's what rrrrrrr actually said and thinks
  [8/31/2011 1:43:17 AM] xxxxxxxxxxxxxx: I'm talking about ps3 dev wiki BTW here
  [8/31/2011 1:43:25 AM] qqqqq: if it's providing false info, then why not make a site to provide the right info? *gasps*
  [8/31/2011 1:43:34 AM] xxxxxxxxxxxxxx: well he did make the suggestion
  [8/31/2011 1:43:38 AM] xxxxxxxxxxxxxx: but it didn't go over well with these people
  [8/31/2011 1:43:45 AM] yyyyyyyy: kkkk wasn't the only one with cex-dex shit
  [8/31/2011 1:43:50 AM] yyyyyyyy: hell he's not even the one who wrote it
  [8/31/2011 1:44:01 AM] yyyyyyyy: so you can stfu about that
  [8/31/2011 1:44:09 AM] xxxxxxxxxxxxxx: hell do I know who the fuck wrote CEX-DEX
  [8/31/2011 1:44:27 AM] xxxxxxxxxxxxxx: all I know is that there are a bunch of connivant shits that want a wiki intentionally 'disinfoed' like that
  [8/31/2011 1:44:35 AM] xxxxxxxxxxxxxx: people in the know
  [8/31/2011 1:44:49 AM] yyyyyyyy: and one conniving shit here trying to save his hide
  [8/31/2011 1:44:57 AM] qqqqq: xxxxxx, again as i said. If there was false info (Which uuuu would never do) Why not fix it
  [8/31/2011 1:45:21 AM] xxxxxxxxxxxxxx: go ask rrrrrrr - I dunno
  [8/31/2011 1:45:26 AM] qqqqq: DO you think he purposesly makes changes so that it's wrong? That'd create an even bigger headache if a noob attempted it and bugged us in the chat
  [8/31/2011 1:45:32 AM] xxxxxxxxxxxxxx: the EID/CEX-DEX info was incomplete
  [8/31/2011 1:45:33 AM] xxxxxxxxxxxxxx: faulty
