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 relates to the way later 2.6 kernels enumerate adaptor ROMs and is not specific to Alpine Linux - see this kernel bug report

To fix this issue, 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
