The original poster has a problem where the BIOS is locked with -1D3B password scheme and the laptop is used. He wants to try reverting to an earlier EFI using the HDR recovery method in hopes it's one of the supported master passwords (ex: -595B, etc.). We are stumped as to what the HDR filename should be and if the END key still works to trigger recovery.
it might not even be .HDR i saw in bios-mods an efi dell recovered but forgot details. BIOS.cap i believe.. but this is not same type.
I'm wondering what is the next thing I should try??? BTW, I'd like to thank all participants who got involved in this thread...
Guys, Can I anyway install win 7 on this Dell's ssd (on other machine) and then to boot it on my locked Dell? I've seen that controller is set to RAID, and not to IDE or AHCI, and I can't change it because BIOS is locked... I've tried and I can't boot windows 7, it appeared blue screen of death and restarted continuously... Is it possible in this way to somehow have a working laptop???
That's the way I usually set up machines, using Ghost to clone the drives which I've put in a usb carrier box, Used it on D610s, D620s, D630s, a Compaq desktop, and a Toshiba notebook Don't know what the Raid setup will complicate, but if it's a reasonably similar computer, I'd put the ssd in a usb carrier box, and ghost the other system to it then boot it to safe mode and sort out the drivers, display will be the most important, you've got to be able to see what you're doing. If you try to boot it to anything but safe mode it will probably give up and give you BSOD. You've got to get the basic drivers sorted before it will boot cleanly. ...T
I'll chime in on this one too. Similar issue with a Dell Precision M4500. Current BIOS A10. Setup is password protected (-1F5A) and locked boot order. Trying to perform a recovery. Extracted hrd file from A09 (for reference) and A11. Inside both I find the name Code: asics0.rom as well as Code: FID.C.asics0 As multiple reports indicate, using END for recovery does not prove useful less the diagnostics it performs. Using PhoenixTools 2.14 seems to have issues extracting HDR file from M4500A11.EXE on my Win7-64, so I used python script Code: C:\Python27>python dell.py M4500A11.exe Decompressed data written to M4500A11.exe_decompressed.hdr This produced an 8,976KB HDR file. I have a 64MB USB I will attempt to format (FAT16 fist, then FAT32. I will use the file name asicsA11.HDR Nothing more useful than whats already been said, but I'm looking.
D610 Problem Solved I've been wrestling for months with this D610 recovery of bios A06 tried multiple flash drives of various sizes FAT and FAT32 formatted spelled the header name in every conceivable way Tried a floppy in the modular socket, didn't work either. tqhoang recently suggested that I try a usb floppy, I did not have one. So I went looking on ebay today and discovered that a modular Dell D class floppy has a mini usb port on the side at the rear, all that was needed was a miniusb to usb cable Short version , I copied the header file to the floppy removed the battery and hard drive attached the usb floppy to the top socket at the rear of the computer held the END button, plugged in the power and it worked, I could hear the floppy engage it just sat there for a minute or so then shut off and when I rebooted bios A06 was restored so A USB FLOPPY IS NECESSARY TO RESTORE THE HEADER ON A DELL D610 ...T
WELL DONE, tonto11!!! I was out of state, so I didn't read your recent posts, but I'm glad you've solved your problem. I'm still stucked with my M4600 locked bios... Have yyou or anybody some more ideas how to unlock it???
Guys, I've installed (copied) Dell's tool from the link I gave you in previous post and I don't know am I allowed to change the service tag and, consequently, to change bios master password??? Did anyone try this tool??? It works, but I can't choose any options (like set or delete asset tag). It just put me back to root folder where is program saved. I'm doing it in DOS.
Exactly What should I do more? I've tried everything and still no progress... My laptop is useless, I can't even install windows because BIOS is locked on RAID, therefore it won't boot up OS...
Guys, I've decided to pay for Dell password. What do you think about offers on Internet which give you a password for 50 bucks? IS IT A FRAUD???
Hi, Does anyone know how to get a 16MB flash file for Dell OptiPlex? I have 4 machines with identical Service Tag and MAC address and they are not working in the same network due to same MAC address. I have managed to read the file, change the MAC address, load it and computer boots, but there is a delay of about 1 minute when computer boots. I tried upgrading from Windows after this but it's acting the same. Next I want to do is download a file from Dell website and put it in the chip and then use Dell CD tool to write Service Tag and some other tool to add MAC address. Anyone can help me find "virgin" Dell OptiPlex 7050 BIOS? I see this HDR but it is 17 MB. Also, 2 files inside HDR are less then 8MB and 3 are in bytes size. Thank you,
likely need intel ME cleaned to boot faster post logo. post original fast booting and the mac address and ill try to change and clean ME
