--gBBFr7Ir9EOA20Yy Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hello Hackers, I have an Asus T100TA Convertible tablet thing that I have been unable to g= et FreeBSD to boot on. I have installed Ubuntu on it with these[1] instruction= s. There was some discussion[2] on getting FreeBSD on this hardware in April, = but the thread sort of died off. =20 The issue with the hardware stems from the 32bit UEFI with no compatibility mode. The BayTrails SOC is 64 bit. There does not seem to be 32 bit EFI support available in FreeBSD currently. The UEFI[3] mentions that i386 support will be added a later tim= e. I also came across this[4] summer of code project that claimed to add 32bit E= FI support. So EFI seems to be a dead end for now, so I thought I would try to use Grub= 2 to boot. I have a -CURRENT amd64 memstick img, I have tried booting it in the usb po= rt on the dock and via an USB OTG cable on the main tablet itself. I have also copied the root partition from the memstick image onto a partition on the internal mmc. I then attempt to boot using the grub cli like so: > insmod ufs2 > insmod bsd > set root=3D(hd0,gpt3) > kfreebsd /boot/kernel/kernel or > kfreebsd /boot/loader > boot Attempting to boot loader results in the grub cli hanging. Trying to boot t= he kernel directly adds a bar of noise at the top of the screen[5] and the pro= mpt hangs. The noise at the top appears to scroll slightly. On the suspicion that this might be a video issue I have tried setting the following loader variables from grub with the following command: > set kFreeBSD.hw.vga.textmode=3D1 set kFreeBSD.hw.vga.textmode=3D1 hw.vga.textmode=3D1 kern.vt.fb.default_mode=3D"1024x768" kern.vty=3Dvt kern.vty=3Dsc Setting these options either results in the same as[5] or no noise added at= the top of the screen. I am at a loss for what else to try, does anyone on the list have suggestio= ns or pointers?
