Dear coreboot folks, I admire the coreboot project because it's a fast and up-to-date open source alternative to the proprietary bios crap provided by many vendors. For this reason I am thinking about using coreboot on my Toshiba A100-151 laptop system since it is not supported anymore by Toshiba and even they discontinued to provide all the old drivers for this model in the support section on their homepage (Thank you, you customer-unfriendly profiteers!). How ridiculous that this company has received the German environmental label "Blue Angel" for some of their products in the past (just a little side note). And even with their locked and constricted Firmware updates I feel somehow as if I should be artificially hindered to use the full potentials of hardware features of my laptop. Just to mention some examples: - I cannot use the AHCI mode of the SATA controller although the mainboard should be able to switch to this mode. There is no option in the bios and it's always locked to IDE mode. Therefore, the performance of my new SSD is artificially limited to a low level. - Even Toshiba showes on their homepage that 4GB RAM memory are supported by the mainboard, I could only use 3GB at maximum, even after installing diverse 64bit OS such as Ubuntu Linux 12.04 and Windows 7. I guess that some of the missing 1GB RAM will be addressed to the OS and to my ATI video graphic card in particular, although it was shipped with 128MB of dedicated RAM. But again there is no option in the bios settings to manage the VGA Shared Memory. - Few time ago, I couldn't enable the Intel VT feature of my CPU. However, I found a workaround by flashing a modded custom bios from another forum which enabled some great features. But unfortunately, there is still no ahci support :-( In short, after reading a lot of tutorials in the internet and trying different solutions in Linux and Windows OS (e.g. using registry modifications, pre-boot parameters in grub2 mainly with the command "setpci" as well as trying a MBR mod at the end), I wasn't successful to enable ahci mode and I recognized in general that the bios restrictions by Toshiba obviously represent the biggest problem. But now to coreboot: So far, I made some first experimental steps by testing coreboot in a qemu environment. At least, in qemu I succeeded! The documentation on the coreboot homepage was of great help. However, I am still unsure if coreboot could work on my machine under real conditions after flashing. And because of my very limmited technical knowledge, I would appreciate some help and advices very much in order to avoid making mistakes or to brick my laptop at the end. Therefore, I hope to meet here some friendly persons who are willing to help. In view of the fact, that my model hasn't been supported yet by coreboot I would like to provide all needed information I could get in the following part (with my personal comments marked by "###“): ------ A very brief description of my system: board vendor: Toshiba board name: Satellite A100-151 ### please, don't get confused because later you will also see the product name "Satellite M110". This is due to the modded bios with advanced features which I have flashed. The right name is "Satellite A100-151". CPU: Intel Core2Duo T7200 ### I have upgraded the CPU.

To end with, I would like to say thank you for your commitment concerning this great open source projet and especially for reading my long message! As I explained I am still a beginner, comming from a completely different working field, but having some ambition to use open source software. I would appreciate your support so that coreboot might natively run on my system. -- With best regards, Daniel
