There's a new bios update for the HP Mini 1000 series, called BIOS F.15. It was already released last August but I only saw just today perhaps owning to my being busy with Snow Leopard.
Click on the image to get to the download page for the BIOS update.
Those who still got Windoze on their Mini's (dual-booting with Mac OS X), you can just boot into that other operating system and run sp45107.exe, (1/1 , 1.12M) to update your system. Remember to keep the Mini plugged into a power source.
Now for those, like me, who have opted to completely eradicate the other OS, you can follow this guide to create a bootable Bart_PE USB.
