I will be interested in the future if these issues with incompatible batteries with the latest BIOS get resolved in the future.

Me too. Just got my hackintosh running smoothly. Don't want to jeopardize that.

According to the Dell site the following issues are fixed:

1."Press F12 key" highlight but not into boot menu while the POST progress arrives to about 90%.

2."rpcnetp.exe" is running when set Computrace as Disabled on Setup.

3.If set USB Storage as 1st boot device, system with usb device (not bootable) can't boot to HDD.

Hardly worth losing the ability to use non-Dell batteries.

I dont think its a question of Do I not want to upgrade to A05?,but rather,Do I want to risk downgrading back to A04?

Alright, since I got embarrassingly trounced on for posting about this in the DM9 Upgrades forum:

I assume A04 has no problems with DellEFI/Netbook Installer. Are there additional steps needed after downgrading to A04 when running OS X, such as rerunning DellEFI/Netbook Installer for regenerating the dsdt?

Those changes for A05 can't the only changes for A04->A05 are they? Dell's bios upgrade site doesn't ever have info on the useful changes.

Sounds like Dell is producing their documentation in China now, not just their hardware.

There is another change in A05 for Dell batteries in that it allows reporting of time remaining and not just percentage as it provides current draw data. However, this also seems to completely hose operations when using non-Dell batteries. I successfully went back from A05 to A04 and have not had any issues.

how did you downgrade from A05 to A04 under Leopard?
a description would be nice.

I am running A04 on my Mini9 and under OSX it shows time remaining. How's it doing it?

Provided by DellEFI/Netbook Installer I believe.
