Thanks Yen. I will try to understand it.
I have read it. I can understand most of it.
Phew, I dont really think I can do it lol. Well it still worth a try
I have been trying this Improved Way to Add SLIC (SLP 2.0) Table into BIOS ACPI to Activate Windows Vista OEM and I have repeated this steps again and again. After flashing the Bios and then using HWDirect to find SLICv or SLIC. I can not find neither..... I am so determaned to flash this Bios myself and see if I can do but no success......is there better translation of the AWARD BIOS perfect activation VISTA Super static? lol...I have no idea what the first part is talking about but the second part does make sense
At the beginning Zhaoliang describes how to extract pubkey and marker from a preinstalled vista bios. You don´t need, cause you have extracted SLIC already!
If you have detailed questions about, please ask.
I modified p5rd1-vm bios 1104.
I have done most of the part as in the guide. Except the part for RSDT and XSDT since the bios does not have these two. Phew, that makes the modifying so much faster lol.
The result, I get the SLIC table at address 00005950. I compared mine with the one modified by XBIOSES, which the SLIC table is at 00005940.
I guess I made some mistakes. Does anyone has any idea?
Also, about calculating SLIC memory address, the bios is 512kb, so
FFF80000h + 5950h = FFF85950h
As I know that address is for the last three pictures as in the AMI guide page 2. I dont seemed to get the use of it. Can anyone explain that too?
??? I extracted 1b module (uncompressed with Mmtool) and had a look with winhex:
There is RSDT table at offset 41D74h and XSDT at offset 41E74h!!!
After inserting Asus Slic as module 23 UNCOPRESSED its place is 5950h. (You have to uncheck writeprotect of bios).
At 1b module the byte after RSDT string is 28h. You have to increase +4 result is 2Ch. Change it.
Now edit OEM table ID beginning with A M I OEMRSDT (start editing "A") with _ASUS_Notebook
Now have a look at XSDT. The byte after is 2Ch. You have to increase table length byte +8 to 34h. Now do the same and edit correct OEM table ID _ASUS_Notebook beginning with "A" of A M I OEMRSDT.
Calculate pointer: FFF80000h + 5950h = FFF85950h (this formula cause your bios is 512 kb)
Now go back to RSDT. Count forward 41 bytes beginning from "R" of RSDT.(R=1) This will be the first byte to insert pointer. Pointer is reversed address of calculated value. Calculated value was: FFF85950h, so reversed pointer is: 50 59 F8 FF. Insert now beginning of offset 41 as said.(here at offset 41D9Ch)
Pointer has to be set for XSDT, too. Count forward 45 (41+4 cause it´s 4 bytes longer) beginning from "X" of XSDT (X=1) and insert same reversed pointer, too (here at offset 41EA0h).
Save changes to 1b. Replace original 1b module with the edited one using amimmwin: amimmwin P5RD1-VM-ASUS-1104.ROM /r 1b 1b.rom (1b.rom is filename you named 1b module by extraction)
Now new 1b module is replaced with original. After that you have to check Slic address (offset) again.
Open P5RD1-VM-ASUS-1104.ROM with Winhex again and search for SLIC. And NOW YOU WILL FIND IT AT 5940h!!!
This is the answer of one of your questions. The address changed from 5950h to 5940h due to compression, which means the correct pointer is now 40 59 F8 FF!!!
Open (extracted) 1b.rom again with winhex and correct the byte at RSDT pointer AND XSDT from 50h to 40h. Save again and replace again (amimmwin P5RD1-VM-ASUS-1104.ROM /r 1b 1b.rom)
YO, now your mod is done.
Now you know what all the modders are doing for all the people
Good luck, Yen
I checked it and IMO it´s modded correctly! You can extract your 1b module and Xbioses and compare with winhex, but I think it´s not necessary. The most important is the pointers position!
I have no idea, why there is MD5 difference.
You did it! Hope this instructions help others, too
Yahooo, finally I did it. Thanks Yen for checking it. I will keep re-mod this bios and when I can do it faster without any problems, it is time to help others modding.
Since there are even differences between the Ami bioses you ´ll need to know more methods to mod. But this one is the most needed. Anyway if you have got more questions feel free to ask again.
256KB => FFFC0000h
512KB => FFF80000h
1024KB => FFF00000h
2048KB => FFE00000h ? - Right?
I am trying to learn AMI bios now so I will to ask questions in this thread. Hope original poster don't mind.
1. Yen, unlike AWARD modding, with AMI when you increase RSDT table length by 4 and XSDT by 8, you do NOT insert the extra 00's bytes at end of tables pushing everything forward, correct?
2. What cases this method can not be used?
3. What compression does AMI use, do you know a manual way to unpack like with AWARD?
4. I know there are automated tools for AMI, but do the modders use them?
I want to feel comfortable with AMI before helping others.
I'm going to mod Asus P5Q bios. Can I use AMISLIC3 tool or another method?
I used AMISLIC3 to mod Asus P5Q PRO 1004 beta bios and when I try to flash it I get message "Boot block is not valid" or something similar.
I flashed P5Q Pro - Ver. 0703: AMI slic = Asus. Mod Fzeven, tst cykelpump, moded by Fzeven and it works fine. So I want to ask Fzeven what method did you use to mod bios 0703?
I know i am ressurecting a very old topic
But, I posted my problem in another part of the forum, but still didnt get answers
I need to modify my bios
its an A1637IMS 1.7, from a MSI PR600 Notebook
I opened the dumped rom with some programs to figure out what i must do, but i am affraid of making some crap and brick my notebook ehehehe
and with AMIBCP 3.37 i found
0x0181 Intel Virtualization Tech
- 0x000 49 6E 74 65 6C 28 52 29 20 56 69 72 74 75 61 6C
- 0X010 69 7A 61 74 69 6F 6E 20 54 65 63 68
But i don´t know exactly if this is the place to change some stuff
i tried to attach the bios file but its impossible to upload (it gets stuck at 20% )
