1. Launch OS image and go straightly into "Troubleshoot" mode for CentOS/RHEL 7.x version. "rescue" mode for CentOS/RHEL 6.x version. Then, select "Install CentOS/RHEL Linux 7 in basic graphics mode" for installation.
2. Load the driver, downloading from
Aspeed website,
3. After patching driver in the kernel, user will be able to launch installation page for the operation system.
Steps for patching driver.
(a) copy AST driver and decompress the driver package
(b) If the driver is correctly mapfolder and run command, ./auto-update.sh
If you have specific kernel version, you will have to perform SRPM with corresponding kernel version mapping to driver source.
(c) Run "rpm -qa |grep ast" to check if it's been fully installed.
(d) Once when the operation is fully installed completely, editing grub to remove "nomodeset" in the grub.
#vi /etc/default/grub
Remove nomodeset parameter from GRUB_CMDLINE_LINUX_DEFAULT line.
Save and exit the grub configuration file.
Re-generate the file for legacy or UEFI base.
(Legacy), please refer to this
#grub2-mkconfig -o /boot/grub2/grub.cfg
(UEFI), please use this
#grub2-mkconfig -o /boot/efi/EFI/(Distros_Name)/grub.cfg
Distros_Name depends on the source you have used. Redhat, it will be redhat for the folder name. centos, it will be centos for the folder name.
(e) After it's done, reboot the system to complete the process.
