Notebook chassis / Barebones / whitebook ODMs
« on: March 14, 2015, 07:20:52 PM »
Here are some barebones/whitebook ODM vendors that I had looked up a couple years ago regarding a similar project idea:

15" not sure that any have backlit keyboards expresscard? expresscard?




I also like the MSI GS/GT/G* 60 or 70 style chassis, which includes more audio ports, but those might only be available as more fully built and expensive configurations than a barebones whitebook.



Bizcom (might be a North American supplier for one of the above, I didn't write that down):

What I had thought about was registering to become a small whitebook studio style reseller, like several others out there that customize a whitebook to customer order. Then go beyond what the ODM may have intended, if contracts don't prohibit that, to swap motherboards, and maybe that's not really much different than partnering with a manufacturer to get chassis without motherbaord either, but may be easier and give more options, even if a bit more expensive. At least this way you are buying without the CPU, hoperfully without OS, etc.and maybe even without hard drive, memory, etc. particularly if memory might be different type (ddr2 vs ddr3 between original and your PPC chip)

I haven't yet checked if the above links still actually work, just a copy/paste from an email to myself from February 2012.

At the time I was looking only for what might be available, and did not get into pricing. I was also looking for particular features, such as 15inch size, backlit keyboard, ExpressCard slot, and maybe some other things that you are not so concerned about. While I was also looking for MXM slot types, it was often hard to tell if a model supported that or not, Clevo sometimes mentioned it in specs.

Another detail is the system cooling. Hopefully one can reuse an MXM heatsink system, but the CPU cooler might need to be replaced with almost the same thing, if the original mounting to theCPU/motherboard doesn't work for the PPC chip size/shape that you have chosen, or if CPU thickness above the PCB surface is different then things might not fit properly between PPC chip and original CPU cooler attachment.

Just FYI, Someone from Amiga forums is working to improve video playback codec and mplayer for Altivec in general, and plans to contribute code to upstream library maintainers so it is not Amiga-specific.

Firmware , Bootloaders / uboot + coreboot

My preliminary investigation into a combination of uboot and coreboot seemed to show that the licenses were compatible. This would be helpful if a southbridge/FCH chip was used together with a PPC SoC CPU. Coreboot supports some AMD and Intel parts that might be useful in the hardware design. Some are supported in open-source modules, some are supported as binary blobs, which are x86 binary, but the x86 emulation in uboot originally intended to run graphic card init ROM code can probably be used for these blobs.

Notebook chassis / without motherboard might be tricky

It may make sense to choose a whitebook/barebones style ODM system in a similar fashion as some small studio resellers do, buying from as close to ODM as possible. Then one normally customizes with a particular CPU, OS, memory, HD etc. and you could skip some of those things, but have to swap out the motherboard. Perhaps then resell the motherboard as a repair part on Ebay or someplace suitable for such things.
