After a bad BIOS flash (or better, a flash of a bad BIOS, ghgh) on my Dell Mini 9 I started searching for a recovery procedure using Phoenix BIOS Crisis Recovery Disk.
But this tool requires an USB floppy drive, as seen on Mydellmini forum. Being this hardware quite hem… legacy+unuseful I managed to create a USB pen drive image that will restore the netbook with the very latest A05 BIOS.
- Download the USB pen drive image here and unzip the file.
- Copy the A05.DD image to your usb pen, using dd on linux:
dd if=A05.DD of=/dev/sdX
replace X with your correct device, of course. Haven’t tried, but this may work also with dd for windows.
Then start the recovery procedure:
- Remove battery and power adapter;
- Confirm USB pen drive is plugged in;
- While pressing and holding Fn & B keys, attach power adapter plug. The power lights will momentarily blink and your Mini will beep once;
- Continue to hold Fn & B and press the power button;
- Release the keys once USB pen drive begins reading (your pendrive led starts blinking);
- Your Mini will beep continually until the flash is completed and reboots.
Note: the display is not available during this process.

It’s an incredible feature I can say. IT is really nice feature. I looked it’s mirror image also it looks fabulous. But ya if it remove it’s small bug that need of floppy drive then it will be more better than wright now.

you made my day with this post.. it really works. my bios crashed, i can’t imagine why … if you make a tutorial how to do this in windows it would be great because tonight i used a live usb ubuntu to do that… anyway..thanks man.

Thanks for the guide, man!
I’m trying to recover my mini BIOS right now. It has been beeping with the screen off for more than 5 minutes now, I hope this is the normal behavior but, boy…it is soooo slow.
fingers crossed.

@victor: mine bipped for no more than 2 mins, doh! Keep me informed on the process…

No luck :-( after an hour stopped beeping, the pendrive’s LED was on (no blinking) and I unplugged it. the BIOS stills KO.
Dumb questions: in which USB did you plug your pendrive? it was a 2.0 or 1.1 USB pendrive?
thanks!

by the way…the beep sequence it makes is 1 long + 2 beeps. (also related to a video card error code…coincidence?)
September 29th, 2009 at 23:12
@victor: usb2 pendrive in the upper left (i.e. the one nearer to the lcd screen) port.
When you hear the 1 long + 2 short beep sequence?

wow man! I did it!! :-)
I don’t know why but the embedded BIOS flash utility didn’t recognize any of my pendrives (I tried with 5 different) in any of the ports.
In some of the tests I heard that beep sequence just when I was supposed to hear the beeps you describe in your procedure.
Anyway, I think it has nothing to do with your flashing procedure. Maybe it was the motherboard complaining about the mess.
I finally downloaded this app:
http://mydellmini.com/forum/dell-mini-9-hardware-issues-problems/8233-dell-i910-mini-vostro-a90-usb-key-drive-flashbios-utility.html
the app generates a bootable recovery floppy disk. I don’t know why but it does not work with pendrives (even if you set the drive letter to a:. Fails when writing the boot record)
So I created a virtual floppy disk drive with:
http://virtual-floppy-drive.uptodown.com/
And used the first app to create the boot recovery floppy on the virtual floppy drive. A
After that I saved the virtual floppy content to a .ima file and used it as a source to burn a bootable CD from Nero (Nero Burning Rom has an option to create boot cds from floppy drives or floppy images)
And then I recreated your procedure with an external USB DVDROM drive (I don’t have a USB floppy reader).
———–
By the way, I’ve linked this page in the mydellmini.com forums, there’s a lot of users with this problem at the forums.
I hope you don’t mind. If there’s any problem just sai it and I’ll delete de link.
Thanks again!

i love this feature, it bring convenient to me.

I’m not familiar with dd.
so what do we copy to the usb pen drive?
is it only the a05.dd, or do we need to copy some dd files?
( I don’t understand what a dd is).
I’ve tried with just a05.dd
and my mini beeps all the time..

Here is how I got it to work after failing many many times.
1. First format the USB pen drive as FAT in windows.
2. Start a Ubuntu live CD and follow this guide to make a USB. (Note if success the USB volume name will be “CRDISK.”
3. Try different USB pen drives, I have three and tried all of them. The one that worked was a kingston datatravler ready flash.

Note also that I tried all USB ports on my dell mini. Right one worked. Left one near screen I think will not work.

THANK YOU!! I thought I had bricked my new Vostro A90! Attempting to flash A03, it froze. Hard reset… nothing. I knew I didn’t want the A05 that this rescue tool uses, so I copied the A03 for the VostroA90 to the pen drive after writing the boot disk image to it. It beeped forever. I copied the A04 for the Mini9 to the boot disk, booted from the right side USB port, waited about 2 minutes and it finally came up… as a Mini 9. Great! Everything is working now. Extended battery at 25% reporting 3:45 until full. Thanks again to the author!

Good post!It works for me!thanks guy!

Thank you, thank you, thank you!!
I could finally revive my Dell Mini with this method. Be careful if you want to upgrade to A06 instead of A05, because simply overwriting the file WILL NOT WORK!!
The files must be present in the floppy drive in a very specific order. If you want to directly upgrade to A06 you will have to follow this guide:

Kind regards.

Hello,
I have a problem. My DELL Mini 9 does not start up. When I press the power button absolutely nothing happens. I tried to do the USB thing. It beeps once when I press the Fn & B keys and attach the power adapter, but my usb does not flash and still nothing happens. Anyone knows how to fix this? Thanks

Well this isn’t working for me. I tried every usb port with no luck. After, holding fn+B then power the mini beeps once the pen drive led flashes once and that it… Screen stays blank and no other beeps. Any help would be appreciated.
May 8th, 2010 at 15:12
I can’t get my mini 9 to even start reading any pendrives. Is it possible that it will read an external floppy even if it does not attempt to read any usb pendrives? I’d rather not buy one if it’s not going to work.

Good share,Attractive enough for me ,thanks for your kind share.

I’ve signed up for your news feed after reading this piece! Would you post more on this subject in future posts?
July 14th, 2010 at 15:22
I’ve followed these steps and it works… it boots to the usb drive, goes through the process of beeping, and restarts.
The problem is that when it restarts, it comes up with a screen that says “Enter Password” and no defaults or anything I have tried seems to work. I’ve even opened up the computer and removed the CMOS battery. No luck. Any ideas?
August 8th, 2010 at 6:45
I have the same problem, but in a Inspiron 1010. Have any idea how to create the USB pendrive image for this model?
August 28th, 2010 at 21:46
Same here exactly. tried all usb no luck. one beep, usb light flashes once then nothing. any help much appreciated!
