help needed for 3 registry tweaks

[framug]

Hello everybody,

Very nice and interresting informations in this forum.

First, sorry for my poor english, I'm french.

I would like to make 3 registry tweaks during unattended installation, silently.

But tweaks depends on the differents PC.

These tweaks are :

1/ CPU L2 cache witch is 256k by default in XP (then, it's ok for a pentium 3 processor but not for a pentium 4)

00000200 hexa = 512, example for a P4 :

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]

"SecondLevelDataCache"=dword:00000200

2/ IoPageLockLimit

values are :

4000 for 128 MO RAM memory.

8000 for 160 MO RAM memory.

10000 for 256 MO RAM memory.

20000 for 512 MO RAM memory.

40000 for 1 GO RAM memory.

example for 512 MO :

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]

"IoPageLockLimit"=dword:00020000

3/ windows kernel and drivers in RAM memory (but, only if greater or equal to 512 MO RAM memory)

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]

"DisablePagingExecutive"=dword:00000001

Then, I have an idea, using CPU-Z software like this :

CPUZ.exe -file=filename

We have L2 cache and memory informations in HTML format :

L2 cache :

Is someone know how to read this file in dos mode (because of tweak for all users in cmdlines file), rescue information and apply tweaks depending on informations rescued ?

Many thanks for your responses.
