A am building low-power server on new Atom-based D510MO with Gentoo Linux. I would be grateful if you help me with some questions.
I disabled VGA using this command:
setpci -d 8086:a001 D4.w=0003 #0003 disables vga, 0000 to enable
To reduce memory usage, I sat VGA Memory usage to 32MB in BIOS
disable everything Audio related in Bios and Kernel, in fact, disable anything you dont need
