coreboot support/port for Asus M3A78-EM matherboard?
by SAL-e 25 Aug '11

25 Aug '11

Hi, I have old Asus M3A78-EM [1] board inside my HTPC. I'm looking to speed up the boot process of my HTPC. I have heard that coreboot can boot directly into Linux or GRUB. I checked the supported list and found out that my board is not on the list, but at the same time I see that very similar board Asus M4A78-EM [2] is on and supported well. So I am wondering how difficult and how much work wold be required to port coreboot to my board. Secondary question would be if I have to upgrade my HTPC witch board would be better for using with coreboot: Intel i3-2100T based system or AMD E-350 based? Thank you, SAL-e [1] http://www.asus.com/Motherboards/AMD_AM2Plus/M3A78EM/ [2] http://www.asus.com/Motherboards/AMD_AM2Plus/M4A78EM/ PS. Please replay directly or CC in your reply to me, because I am not member of the list yet. 10x

Do they preinstall coreboot from factory already ?
by xdrudis 24 Aug '11

24 Aug '11

I've just seen these news about a new vehicle PC with 5 seconds boot time thanks to coreboot, but there is no information on pricing, software (if any, maybe it is sold without hard disks ?) or firmware (apparently they would ship it with coreboot, but the datasheet does only say "supports AMD Coreboot technology", which might mean that the user can install it and it should work, although I'd think it's more likely to mean it comes preinstalled. If so it may even be tempting. Pity my only vehicles are bicyles and I'm not sure what to use the 1.5 kg + disks + screen+ power source for while riding... I guess you can also use it at home, but I wonder about the price (no , I'm not going to ask them because I wasn't thinking of buying a new computer now, but I'm curious). http://www.linuxfordevices.com/c/a/News/Portwell-PCS8277/ http://www.portwell.com/products/detail.asp?CUSTCHAR1=PCS-8277#order In any case, congratulations all, it looks like another milestone. Time to start a new section in the web about "where to buy?"
