I just installed Ubuntu in my Compaq Mini 110C, I will write here my comments.
First I tried Ubuntu Netbook Remix 10.04, I followed the instructions in Ubuntu site and used a USB stick.
I booted from the USB stick, used Gparted to shrink my windows partition and later installed Ubuntu from the USB in the unallocated space.
Almost everything was ok but my wireless card was not working ok. Also sometimes the notebook was not booting (blank screen and cursor blinking).
Anyway I wanted the standard Ubuntu menus and more than one desktop so I thougt about giving a try to “normal” Ubuntu.
I formatted again my stick and downloaded an installed Ubuntu. I did not realize about performance differences and this I liked best so I googled a bit about my problems.
I had three problems: the wireless card, the blank screen (not on every boot), and also a message in the logs:
"Atom PSE erratum detected, BIOS microcode update recommended". I could find help in internet about all of them.
I fixed the problem of the wireless card using the Broadcom STA wireless driver. It seems the wireless was the cause of blank screen too.
For the CPU microcode error, I booted into windows, downloaded and installed the last BIOS version, reboot and the error was gone.
So now I am using Ubuntu and learning about it.
