Hello, I try to update BIOS on Dell Latitude E6330 by file *.EXE on official website. During the update, around 30% it shut off, and now won't turn back on. I'm sorry for my english. Thank you for any support.
Not sure I understood your question. As for extracting BIOS from the said exe... The BIOS exe file one can download from Dell's support website, DOES NOT contain the full BIOS image (there are two ICs in the said model - one 64Mb for the main BIOS (of which only 8 megs are used) and 32Mb one for EC (of which only 4 megs are used)). Here what it contains when extracted with Dell_HDR_Extract (BIOS version A21 shown). Which is Code: //section_0_A.21.data/meta/mtsg/sign System BIOS (new modules + complete EC IC dump) //section_1_A.6.data/sign Embebded Controller ROM //section_2_0.D.3.data/sign Gigabit Ethernet ROM //section_3_2.1.3.7.data/sign Legacy Video OROM (option ROM) //section_4_11.0.1.1392.data/sign Legacy RAID OROM (option ROM) //section_5_8.1.72.3002.data/sign Intel Managment Engine Update ROM //section_6_0.0.0.1.data ACPI OS support //section_7_3.0.0.18.data Intel AntiThieft //section_9_1.0.0.0.data Confirm BIOS Replacement window BIOS version, model name, etc. section text //section_10_1.0.0.0.data Confirm BIOS Replacement window "what's new" section text As one can see, included are: updates for BIOS modules, updates for ROMs, IME and a compete EC flash image/dump. Nope no 8Mb main BIOS dump here. So getting dumps from ICs by some means, is the only way to get the main BIOS dump. One can probably create BIOS with FIT, but I don't know how. In order to avoid the issues with BIOS updates (as mentioned in my previous reply), it is NECESSARY to replace the ME region in the main BIOS IC dump with the "clean" ME region extracted from Dell's BIOS_update_exe file (make sure you download the SAME version of the BIOS as BIOS in the dump you are going to flash). Otherwise system specific data stored in the ME region will cause IME failure to function and subsequently make BIOS updates to fail no matter what. Another side effect of IME not working is absence of IME device in the Device Manager or inability of IME tools to detect any IME device in the system (be it DOS or Windows version). Contrary to most other PCs, non functional IME in case of E6330, will not cause any noticeable issues (apart the mentioned above). On other systems it might show as: self shutdown after 30 minutes (even when IDLE on BIOS screen) fan speed issues Since this notebook has firmware protection in place, it is complicated to flash any modified/non modified BIOS using software methods such as FTK or FPT (say to flash BIOS with "clean" ME region on an already working machine on top of one with "dirty" ME region). Luckily the said model has a hardware option to disable firmware protection. There is a resistor which needs to be moved in order to do this. Here are some pics This will pull HDA_SDO signal high, thus disabling protection at hardware level. With protection disabled, one can flash modified BIOS with ease.
when doing a new DELL bios, I always make a USB image first.... infact you can have more than 1 (compressed) on the same USB. just uncompress what you want to use.... DELL is and has been FAMOUS for years, or Woops blow another bios update....and i have found that many DELL have had poor to worthless battery s from day one....
Yeah, true. In the process of fixing that notebook, I've managed to find a newer BIOS dump (A06). Although it didn't fix the issue initially, after replacing ME region and flashing modified BIOS back, things returned back to normal. Worth noting though, that through the BIOS update sequence (it went like this A06 > A08 > A14 > A20 > A21), only after update A21 IME device finely appeared in the Device Manager. True! Hence there is no A07 version on the website present
