Andres ZeroCross Posted November 4, 2015 Author Share Posted November 4, 2015 Same here,, i have modified my bios (Gigabyte Z170-HD3) and get error "error: Problem getting flash information" I used Gigabyte Flash Utilty and AFUDOS Link to comment https://www.insanelymac.com/forum/topic/308707-fresh-install-from-usb-installer-el-capitan-10111-beta-build-15b38b-on-skylake-i7-6700-gigabyte-z170-hd3/page/8/#findComment-2185290 Share on other sites More sharing options...
dreamcat4 Posted November 4, 2015 Share Posted November 4, 2015 Tony from the other side just confirmed that Gigabyte is aware of the issue and will be issuing an official BIOS update to disable the IOAPIC setting. I'm waiting for that rather then messing up my motherboards BIOS. Ahem... We mean *enable* this feature, don't we? As it's already disabled by default? --> http://i.imgur.com/75ocC7q.png Link to comment https://www.insanelymac.com/forum/topic/308707-fresh-install-from-usb-installer-el-capitan-10111-beta-build-15b38b-on-skylake-i7-6700-gigabyte-z170-hd3/page/8/#findComment-2185322 Share on other sites More sharing options...

As it's already disabled by default? --> http://i.imgur.com/75ocC7q.pngI'm pretty sure we have to disable the feature. The failsafe option is to disable it yes, but the 'optimal' option - which the BIOS sets itself to I assume - is the one that is enabled by default. Gigabyte will most likely bring a BIOS update to make this setting changeable.

nexx892 Posted November 4, 2015 Share Posted November 4, 2015 I think I found safe way without modifying BIOS on gigabyte motherboards. Use "Save Profiles option," edit the save file and then load it. I believe this saves all settings in a certain format, even ones not shown in bios. Will be a few hours before I can confirm though. 1 Link to comment https://www.insanelymac.com/forum/topic/308707-fresh-install-from-usb-installer-el-capitan-10111-beta-build-15b38b-on-skylake-i7-6700-gigabyte-z170-hd3/page/8/#findComment-2185365 Share on other sites More sharing options...

That sounds like a good plan. I'll give it a shot after work as well. Hopefully it isn't to painful to modify these saved profiles.

yassinex Posted November 4, 2015 Share Posted November 4, 2015 Imho, the solution is simply to boot with the secondary Bios (FailSafe), as in FS this option is disabled. You just need to swith the jumpers position in the MB. I'll try it when I get home :-) Link to comment https://www.insanelymac.com/forum/topic/308707-fresh-install-from-usb-installer-el-capitan-10111-beta-build-15b38b-on-skylake-i7-6700-gigabyte-z170-hd3/page/8/#findComment-2185380 Share on other sites More sharing options...

Xavorithre Posted November 4, 2015 Share Posted November 4, 2015 Yes. I'm guessing you'll do more harm than good if you go about that way, there are a lot of settings that will change if you put them all into safe mode. I suppose it's better just to modify the BIOS or wait for Gigabyte to upload theirs.

Pike R. Alpha Posted November 5, 2015 Share Posted November 5, 2015 Ok guys. I have had a very, very, busy day and that basically delayed everything, but here it is. This is what I have come up with. In /System/Library/Extensions/AppleAPIC.kext/Contents/AppleAPIC You search for: C1 E8 10 0F B6 F0 and replace it with: BE 17 00 00 00 90 That gets me to the single user prompt without delays. Also boots the installer on USB thumb drive and El Capitan on a SATA SSD. Please confirm. 7 Link to comment https://www.insanelymac.com/forum/topic/308707-fresh-install-from-usb-installer-el-capitan-10111-beta-build-15b38b-on-skylake-i7-6700-gigabyte-z170-hd3/page/8/#findComment-2185480 Share on other sites More sharing options...

I mean the full and EXACT steps. All of them. For example I'm concerned when loading my BIOS file AMIBCP says some error / warning with exclamation marks etc. For example it would be more reassuring to see you did/didn't get that (if ignored and flashing was successful anyway).
