Here's a nice candidate to build a LinuxBIOS laptop.
The site is currently /.ed but the specs are:
ECS announced recently its DeskNote i-Buddie A980 mobile desktop PC, the first ever mobile barebone computer. It features no display, no CPU, no RAM and no HDD, but only the case with keyboard and touchpad. The indisputable trump of the novelty is that you are free to install the most high-end and cutting-edge hardware, or you may buy not really expensive components that are enough for your needs.
Here is the list of i-Buddie A980 technical peculiarities:
* Supports Socket 478 Pentium 4 / Celeron processors with 400/533MHz FSB with 3.06GHz clock-speed and above; * SiS650 chipset with SiS962 I/O controller; * 1 DIMM slot for up to 1GB of PC2100 or PC2700 DDR SDRAM memory. * Integrated graphics core, ability to install NVIDIA GeForce4 Go420 mobile graphics card. * 2-channel ATA-100/66/33 integrated controller; * Includes an 8x DVD-ROM drive; * Free bay for 2.5 HDD; * 4 USB 2.0 ports; * FireWire (IEEE1394) port ; * IR port with transfer rate up to 115.2Kbit/s; * 10/100Mbit/s Ethernet adapter and connector; * Integrated 56K modem; * 6-channel audio solution and built-in speakers; * Size: 342mm (W) x 300mm (D) x 34mm(min)/50.5mm(max); * Weight: 1.8Kg.
End-users have a lot of opportunities to expand and configure such computers, they even now can choose between 14 and 15 TFT panel, what should allow ECS customers to get the most cost-effective solutions possible.
According to this French web-site, such barebones will be priced at $300. Not expensive, I believe, but remember that you will need to get a display, a microprocessor, a memory module and a hard disk drive to make it functional.
