That module should be available.

OK, one other tidbit: The EFI BIOS has a UUID in its boot options. I expect that this identifies the old system disk, but I don't know where that UUID comes from. It is NOT the VFAT UUID for the EFI partition and is not any of the UUIDs for any of the Linux file systems or RAID arrays, or really anything else I can find under Linux. I'm guessing it is something the EFI BIOS has

That's what I meant, I think.? Legacy mode is BIOS-compatible.? If you're

I have installed dom0 Wheezy 64 bit on Dell PowerEdge T310 with kernel from package and xen-unstable. System is in Uefi mode and booted with grub-efi-amd64. Booting without xen efibootmgr works, while with xen not, efivars kernel module is loaded but show this message: efibootmgr Fatal: Couldn''t open either sysfs or procfs directories for accessing EFI variables.

I am running an Intel x64 machine using UEFI to boot an SSD. Installing the latest yum update which includes grub2 and kernel 4.18.0-193.14.2.el8_2.x86_64 renders the machine unbootable, blank screen where grub should be, no error messages, just hangs. After some hours I managed to modify another bootable partition (containing older software) and boot it from there. After that, I? found out

I am wondering about updating the version of Spam Assassin on my CentOS 5 mail server. The current version, 3.3.1-4.el5 (stock RHEL version), has been 'leaking' recently. I suspect I need some newer match rules to detect some of the newer flavors of spam. I see that in rpmforge's extras repo is version 3.3.2-4.el5.rfx -- is this version worth installing? Are there even newer versions

I have two computers: both running CentOS 6.7, 64-bit, with kernel 2.6.32-573.12.1.el6.x86_64. One is a laptop with an 2 core Intel processor and the other is a desktop machine with a 4 core AMD processor. Both with selinux enabled. I have a USB serial port device (a RR-CirKits LCC-Buffer USB). On the desktop I am getting this error: sauron.deepsoft.com% sudo minicom Device /dev/ttyACM0

I did a yum update on my CentOS 6 laptop and it upgraded Firefox to 78, and FF stopped seeing my mic and speakers. Is there some magic I need to do? As a short term (?) fix, I downgraded back to Firefox 68.

Different distros have different defaults. There's no actual right or wrong here. Pretty much anything you can think of can be made to work.

Sorry thinking about this problem at work, I'm using my cellphone. Won't get home until 1am. I run Gentoo. https://wiki.gentoo.org/wiki/Syslinux#Setup_on_EFI_systems is my distribution instructions on installing Syslinux. http://www.syslinux.org/wiki/index.php?title=Install#UEFI are your instructions. I have tried both instructions only to get a blank or black screen. Trying to make a

Morning all, I have a HP Envy dual boot system (Win8 for serious stuff, i.e. Train Sim and Flight Sim) and Centos 7 for everything else. In the past I've had the occasional problem where an update on the windows side has updated the UEFI boot sequence but using efibootmgr has always fixed it. On Friday I discovered that my HDD was failing so I tried using Clonezilla to move it on to a new

All of the following is still under the Centos 7 KDE Live CD: If I mount /dev/sda2 on /media and have a look, this is the valid EFI filesystem, including the Fedora and Centos entries. If I try to mount /dev/sda6 on /media it looks to be a valid /boot filesystem. If I mount /dev/sda6 as /boot and mount /dev/sda2 as /boot/efi before running Jim's efibootmgr command will I fix the problem
