please explain to me the structure of ps3 idps

[spyrosfar123]

I am interested in the last few bytes of the ps3 idps. According to devwiki it is the following:

00000000 00 00 00 01 00 89 00 0B 14 00 EF DD CA 25 52 66 .....‰....ïÝÊ%Rf

• 1st and 2nd bytes represent the magic (always 00 00)
• 3rd and 4th bytes represent the Company (usually SCE)
• 5th and 6th bytes represent the Product Code
• 7th and 8th bytes represent the Product Sub Code
• remaining 8 bytes are parsed by bits not by bytes (see IDPS#IDPS second half)

it says:
14 00 EF DD CA 25 52 66 <- Second half: factory code 5, no Ps Flag, serial number 61405, random stamp CA 25 52 66

• Byte 8 bits 0-5: Factory Code
• Byte 8 bits 6-7 and bytes 9-10-11: Serial Number
• Byte 8 bits 6-7 and byte 9 bits 0-5: Ps Flags on PSP with Diag Factory Code
• Bytes 12-15: Random Stamp (guessed name). 3 theories: 1) totally random number, 2) hash of previous bytes (then there would exist at least 3 keysets), 3) encrypted timestamp.

So my question is what is factory code 5, no ps flag?, and where does he get serial number from??

This is a valid critic (i dont understand it either), but you should publish your doubts in the wiki IDPS page to motivate the person who wrote that (CelesteBlue) to improve the description and to explain it in a more "newbie friendly" way
