Installing and Maintaining Gentoo on a Toshiba A45 Series laptop. introduction: These Laptops are not considered quite out of date however with a memory upgrade to 1GB or more and a newer ATA5 160 GB 5400 RPM HD it is a quite nice portable UNIX like work station. All of the hardware on this laptop is well supported and works in linux. This Guide at best can only supplement the Gentoo x86 installation guide and point the installer to other guides worth considering for the following:
Models include A45-S120, A45-S1201, A45-S1501, A45-S130, A45-S1511, A45-S151, A45-S1211, A45-S121, A45-S1202, A45-S2502, A45-S1301, A45-S2501, A45-S250, A45-S150
- Read over the Gentoo installation Guide. The installation guide may fall a little short on encryption. If you want a encrypted system you may want to stop here and look over: SECURITY Encrypting Root Filesystem with DM-Crypt with LUKS. At minimum encrypt the /home partition making it as large as possible so you can configure programs that would normally use /var to use /home.
- Begin the installation process up to installing the Kernel. Use the Gentoo Install CD or minimal install cd. There is a option when booting the install CD so it runs in memory and you have CD drive available for extra CD's with wireless driver packages like ndiswrapper you might want on them.
- See the TuxOnIce guide and use that kernel. It is better designed for laptops.
- Configuring the Kernel:

Wireless: The A45-s120 did not come with a built in wifi. The A45-151 has the following hardware
| Code: Wireless hardware info |
0000:01:05.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01) |
If this is your case see the wireless section of the wiki: MadWifi. emerge madwifi-driver
Display / GUI environment: I have not figured out how to get KDE and Xorg-X11 to use the intel 855GM chip for a big wide desktop but believe it to be possible. General A45 Support can be found here: http://forums.gentoo.org/viewtopic-p-3726820.html#3726820
