|
|
Hello,
My keyboard is disabled during booting gentoo from CD minimal or usb bootable disc.
I tried also sysrescuecd on usb with same effect. I am not sure maybe I got disabled some option in BIOS, or I have fake keyboard
my mainboard: gigabyte 970a-ud3p
any ideas ?

manufacturer, make, model, connection type of keyboard?
do the keyboard leds light up in the first moments of booting? can you use del, F1, F2, or F8 keys to enter bios?
cheap (I have several working for years now) ps/2 wired keyboards sell for 6 dollars and up around here. _________________ Defund the FCC. |

Have you tried several USB ports?
I had the same problems with a speedlink keyboard, which needs an extra kernel module *sigh*
The module was called hid_sunplus
I don´t know if it is already included on your livecds. |

keyboard working fine in bios menu, it fails - together with mouse after I started linux booting process.
IOMMU option in BIOS doesnt resolved problem. |

I have the 990fxa-udp3 rev 4
To get usb and networking I had to:
Enable the iommu in bios
Add iommu=soft to the boot line in grub
Edit: setting xhci and ahci handoff (or legacy or something) in the bios may also help. |
