So I got sick of various frustrations I was having with the stock installation on my HTC Touch Pro (CDMA). I finally installed MightyROM, it was quick and easy. Looks pretty slick so far, more details later.

I recently purchased an 8 cell 77 watt-hour battery from China via ebay for use with my Dell Inspiron Mini 9. This is up from the stock 4 cell 32 whr battery that it came with. I like the new battery so far, it about doubles the weight and size of my Mini, makes the mini look like it is on a stand, or plugged into a docking station — which actually improves ventilation. As a result, the screen doesn’t open up quite as much as it used to, but it hasn’t bugged me yet.

The ebay post said “only works with Dell Mini Bios Verson A00″. Wow they weren’t kidding. I have A04 (was planning on the A05 upgrade at some point), and upon insertion of the battery, it looked to charge and was fully functional, but the LEDs were going crazy! Flashing red and white, they really wanted you to know that this battery is not supported. The flashing was annoying enough; if there was no other issue with this battery I would have still wanted to downgrade to get it working right.

So I was able to locate on the mydellmini forums a utility that someone (somms?) put together called flashBIOS. This app has the capability of creating bootable media (I used a usb thumb drive) with a dos BIOS flashing utility. It even comes with all of the Dell Mini 9 (and even the Dell A90) firmware versions out to date. This is a sweet app, had to archive it.

Download flashBIOSv1.51.exe

It really is self explanatory. Start up the app, follow instructions and flash. I was down to A00 in less than 10 minutes after downloading this.
