Hi everyone,
I'm trying to installing Gentoo but as soon as I boot the kernel from grub when it loads the system can't find media and can't find a root block device and prompts me "press Enter for the same, type "shell" to enter in a shell, type q to skip" (or something like that, i'm not reading the error but was something like that)..

The bad thing is that I cannot type anything because my usb keyboard stop working.. It's still powered up because the leds are lighted up but my system doesn't recive any input from it... I cannot even disable/enable caps lock or any toggle..

Also I think that it isn't a problem like "correct root block and the keyboard will work later when the modules will loads" because before this error the system asks me for the keyboard layout (but i cannot choose it since my keyboard doesn't work )

Please someone help me :(

elkiwy,

Welcome to Gentoo.

In your BIOS, make sure you have Legacy USB Support on.

elkiwy,

OK, lets start again. You want to install Gentoo on a Asus vivotab smart tablet.

Tell what boot media you are using and how the boot media, mouse and keyboard are all connected to the tablet.
Your tablet will be UEFI only, so you cannot use the Gentoo liveCD to start from as it does not yet support EFI.

System Rescue CD is a much better place to start.
Its a Gentoo derivative and allows you to follow the install guide.

Well.. I already tried the system rescue CD but it also has problems with my tablet.. When I boot the kernel it doesn't show anything and the screen stop responding.. I think it's probably a rendering problem. But I cannot find a solution for that too

elkiwy,

I suspect your tablet wants to boot cryptgraphically signed code only.
You must turn that feature off in the BIOS before anything other than Windows will boot.

I already disabled all the things that could cause problems with Linux in the UEFI/BIOS.. And I think that I did not have that features in my uefi..

I start to think that will be impossible to install it.. It's like 10 days that I'm trying everything to install gentoo on that stupid tablet :cry:

Don't lose hope it will happen and the forums are great at support.

Maybe double check your BIOS for Neddy's suggestion. I had the exact same problem sometime back and was bounced to the same prompt you are describing because it was looking for crypto signed code.

Ran into that issue I think. If your tablet is one of those Bay Trail Atom tablets, likely you have xHCI ported to your USB port, and despite it not being USB3 you still need to build xHCI into your kernel. Ran into that issue while building mine...

Now me... I'm stuck at the touchscreen now... This however seems to be an impossible task to solve... :(

Just checked right now and there is no option about crypto...
And for eccerr0r , I have no idea how to build xHCI in my kernel ( And also by the way I have an Atom z2670 clover trail, not bay trail :cry: )

elkiwy,

I'm guessing .. it may be called something like Secure Boot. eccerr0r might know.
xHCI is not your issue yet. Its already built into the boot media.
This is one to keep in mind when you build your own kernel.


eccerr0r,

Touch screens used to be serial or serial over USB but that was before multi touch.

Actually it should not be secure boot. At least my fresh off boat tablet even had secure boot turned off when I got it, it's also UEFI32.

If you can run grub from install media, that's sufficient to say that secure boot is off. If secure boot is on, it should instantly tell that grub is not signed and will fail.

I thought that most of us who are trying to run on these tablets have to build our own kernel and boot solution as Gentoo does not have UEFI32 boot media yet, and the system rescue CD I thought is amd64 which also won't work as is. Are you using a prebuilt kernel? I thought pretty much the only available prebuilt is Fedora's fedlet kernel...

xHCI is one of the USB host drivers in the USB menu in the kernel configuration. It normally is associated with USB3 but on my tablet, I needed it for USB2 as the silicon is a xHCI controller. Without the xHCI driver, I could not use my keyboard or USB peripherals (the boot logs indicated it did not find a EHCI, or normal USB2 controller). I 'm not sure what the z2760 uses however, it's worth a shot to try anyway.

Hmm ISTR that likewhoa got somewhere with EFI for the live-dvd's in #gentoo-ten as people were using them on Macs with EFI (I think.) He definitely makes them suitable for USB usage, though you'd have to get the exact command from the channel.
