From Go-OS

July 4th 2008, Paris, 9:00 AM on Panasonic CF-R6

First test of Go-OS on real hardware : a Panasonic R6 bought from an online geek shop based in Japan.

Of course it doesn't start, we didn't code drivers for this computer, but seeing that our IRQ system, our modules sytem, our bootloader system, etc... works on some real piece of hardware is a real bliss.

TODO

• It seems that hard disk detection is wrong. I guess the internal SATA controller emulates standard IDE adapter, however the disk isn't a 615MB hdd but a 160GB hdd, we need to check that.
• We need USB driver to load other drivers
• We'll need a gfx driver for this piece of hardware

IDE Debug

It seems that the whole IDE block is not reliable. We should avoid using it :)
