Dear Serg008, I finally found where the key point was and have solved it just now. I found out that the upgrade was in fact succeed, but the bios's display driver could not work, so screen was keeping blank after the upgrade. CMOS was reset, and the HARDDISK SATA MODE was reset to ACHI too, while, my windows XP is working at a IDE mode, and surely could be booted at a ACHI mode. No screen, no beep and no OS vioce too, and so I mistook it as a bios upgrade failure. Fortunately, I found something different when I PRESSING F2 KEY to POWER ON. My Harddisk led just flashed once or twice, and later kept off. It seems like I had entered the bios normal setting mode. BIOS IS WORKING, BUT JUST NOT FOR SCREEN. I succeed to set the bios to multi-boot mode just by my memory, and made tries pressing F12 and DOWN key to boot from my U stick, and finally booted up an DOS operation and it's autoexec.bat to automatically flash an official bios of VER. 2.01. My AS4750G Notebook is working well now. I am sure that I upgraded from the modded bios of VER. 2.01 (POST #7793) from official of 1.23 for my AS4750G,and still don't know what the really matter is, although I recovery my bios.
For mr-smith: I might be getting this motherboard from Scan next week. I am uncertain as to whether it has been replaced with the P8P67 Rev3.1 - I know it has to do with the USB3 control chip. If I get V3.0, I'll flash as per serg008's link and post the result.
I am planning on flashing my HP (Asus) IPIBL-LB BIOS (AMI) and found the latest version (5.43) mod on this thread, and it was confirmed to work by a couple people. I already have flashed the 5.43 (un-modded) BIOS from HP. I tried modifying it myself using AMITool (SSV3 + MMTool) and it said successful, however I have not tried flashing BIOS with it. My question is... I compared the modded BIOS I got from this thread, which was also modded by NoJuan999 using SSV3 + MMTool, with my own modified BIOS and out of curiosity compared the two using WinDiff and DiffVue Hex Comparison. The two modded BIOS were different and I guess I am curious as to why? I modified the original BIOS from HP twice, once using AMITool 1.32 and again using 1.61, and comparison showed they were identical. But when comparing to the modded BIOS from this thread, they are different. I'm not questioning the BIOS from this thread... I guess I am more interested in knowing what the difference is so in the future I would feel more comfortable modifying other BIOS myself rather than seeking out a mod on the web. Any ideas? Is there a different modding utility I should be using? The modded BIOS from this thread is for CPC, which is what I need according to Everest Ultimate. Is it possible the HP info that comes with AMITool are not CPC? MPC maybe?
I just flashed with the modded BIOS from NoJuan999. I planned on using that one anyway because it was confirmed to work, and I'm sure he is more knowledgeable about modding it than I am. The flash worked great. I used AFUWIN (yes, from Windows) because that is what the update from HP uses and personally have never had problems flashing from Windows (with as much turned off as possible). I only updated the main BIOS image, leaving the boot block alone because from what I understand that was the safer move. So the only options I selected were main BIOS image and clear CMOS checksum if that helps anybody with this board/BIOS. I had already flashed to the 5.43 version anyway so did not expect the modded 5.43 to change a whole lot. The mod from NoJuan999 I found here: forums.mydigitallife.net/threads/7500-All-Slics-2.1-(Modded-Bios-List)-Note-For-requests-use-Bios-Mod-Requests-section/page461?p=311645#post311645 The 5.43 I modded with AMITool is here: badongo.com/file/25635644 If anyone can tell me the difference, or if it is probable that either one would have worked, that'd be great. I have a few other computers I would like to try modding myself if I know that I am doing it correctly. Thanks...
You say you modded the bios using the SSV3 and the default MMtool. As long as you didn't see any errors your mod should be ok. When ever modding always disable your AV. I still don't no what you mean when you say they are different. Both bioses are the same size. Unfortunately bios modding and updating the bios carries risks. Without having the same motherboard as yours its difficult to say whether your bios mod is good or bad. All bios mods offered here carries risks. Thats why feed back is so important as in the case of the modded bios at MDL. You really need to read the stickies and ensure you have a backup plan for recovery should something go wrong. I did my first bios mod on an old MB i intended to scrap. I certainly wouldn't take the risk on my main machine as a first time mod. And finally no one will be able to offer the re-assurance you request on the mod you carried out. The result will only be known fully on flashing the mod. If your motherboard is for your main PC and as you say you have flashed the mod from NoJuann999 then the additional risk is probably not worth it. Do a search to see if anyone else has had to recover from a bad bios. This would be a start for a backup recovery plan should things go wrong. I am really sorry i cant offer you any further advice
