When using the BIOS block driver, the system freeze at boot while trying to read the disk, the HDD led just stay lit, and nothing happens.
When using the IDE/ATA driver, the system seems to boot, then just reboot, probably due to a triple fault, we need to implement console scroll to get all debug.

BombStrike: /* Let's emulate 16bits BIOS for VESA */

[[image:Revision357 on real hardware.jpg|right|thumb|250px|五OS on Panasonic CF-R6]]
== Panasonic CF-R6 ==

This is our first test hardware for 五OS. This is a nice 900g laptop from Japan, with a Intel Core2DUO 1.06Ghz and 1GB RAM. This model is sold with a 80GB hard disk, but our laptop has a 160GB western digital hard disk.

Test boot is done via a 2GB Sony "Micro Vault Tiny" USB key, where we write the 五OS disk image. The BIOS boots the USB key as a hard disk, and we take over from there, using our (future) usb driver.

== Hardware ==

* Intel(R) Core(TM)2 CPU U7500 @ 1.06GHz (64 KB L1 cache; 2048 KB L2 cache)
* 1GB RAM (2x512MB)
* 1 PCMCIA Slot
* 1 RJ45 connector
* 1 RJ11 connector (internal modem)
* 1 SD-Card slot
* 1 Wireless LAN

=== AHCI debug ===

We started our AHCI driver. Here's a debug output on real hardware for [[BombStrike]].

[[Image:Revision377 on real hardware with AHCI debug.jpg]]

== Attempts to get this hardware working ==

=== Let's emulate 16bits BIOS and access disk ===

That's a good plan, however it seems that emulated BIOS don't like doing int 0x13[ah=0x42] :(

[[image:Revision523 with emulated blkdev bios.jpg|250px]]

=== Let's emulate 16bits BIOS for VESA ===

Seems like 16:10 VESA resolutions don't works with function 4F03h of the VBE specs... Well, the normal resolutions still output nicely :)
