Hardware support

The hardware support is indicated in the table on the right.

Fan throttling

The fan can be controlled (throttled) in software, otherwise it never shuts off, even if the BIOS option "Fan always on while on AC power" is disabled. There are two programs supporting the 4330s:

Intel CPU microcode

See Microcode#Installation.

Synaptics Touchpad

The xf86-input-synaptics driver is needed (see Touchpad Synaptics) for the touchpad to work, but the pointstick works out of the box.

WLAN BIOS whitelist workaround

HP BIOS allows only certain WLAN cards (whitelisting) to be used. This can be worked around by adding the following as the first GRUB command in every OS entry:

write_dword 0xFED1F418 0x1F501FEB
