Installation

Boot from hardisk does not work

If your bootloader is located not on the first physical disk, this option will not working.

System boots into the 'Live' mode after reboot

After system installation is complete and you reboot the machine, do not forget to eject your installation DVD or USB media, since by default the 'Live' mode will activated. Alternatively, you can change the priority of boot devices or choose 'Boot from hard drive' when booting from the installation media.

If installed from USB Flash, the system displays a message about 'Emergency mode'

If you install the system from USB Flash, you can a message about 'Emergency mode' after removing installation media rebooting. If this is the case, just insert the USB Flash back, load from it, choose 'Boot from hard drive' and finalize the installation (there will be several question from wizard). After that, you will be able to boot the system normally.

If you have Windows partitions, you may need to load Windows and run scandisk.

Incorrect resolution with Intel graphics cards

If you have a modern Intel graphics card, you may need to delete the following parameter from the boot loader menu entry:

nomodeset

Very long boot time with VMWARE installed

In case your boot takes very long time you can try disabling pcscd service in your host system. It can be done via drakxservices, or by executing command

systemctl disable pcscd.service

from root user.

Adaptor ROM Conflicts

This information relates to error messages such as the one outlined in the page title and other similar ones - for example:

pci_root PNP0A08:00: address space collision: host bridge window [mem
0x000cc000-0x000cffff] conflicts with Video ROM [mem 0x000c0000-0x000ce9ff]

This error message occurs due to latest kernels enumerate PCI host bridges and is not specific to ROSA Linux - see this kernel bug report. The message itself does not indicate a functional problem, so it can be ignored.

If you see additional problems, such as computers with multiple NICs not starting all adaptors reliably and issues with multi display/adaptor configurations, please report them in the kernel bugzilla and attach a complete dmesg log. The pci=nocrs parameter may be a workaround while debugging the problem.

To use pci=nocrs, edit the syslinux.cfg boot file and add pci=nocrs to the parameters. On systems that boot from a USB memory stick, this file is /media/usb/syslinux.cfg Example:

timeout 20
prompt 1
default grsec
label grsec

kernel /boot/grsec append pci=nocrs initrd=/boot/grsec.gz alpine_dev=usbdisk:vfat modules=loop,cramfs,sd-mod,usb-storage quiet

Cannot install system with /var in a different partition than /

Error "cannot copy files to new partition" in the end of the installation process. The error occurs because of squashfs installation image which contains hard links to other root directories. Solution: keep /var and / on the same partition or disk.
See also bug #316.

Hardware
