| === Boot Alpine Linux CD-ROM ===
| | {{Delete|This include has become obsolete. It is completely unused on the wiki}} |
| # Insert the Alpine Linux CD-ROM into a computer.
| |
| # Boot the computer from the Alpine Linux CD-ROM.
| |
| #* This step may require changes to the BIOS settings to select booting from CD.
| |
| # Login with the username ''root''. No password is needed.
| |
| | |
| {{Tip|If you're not able to boot from the CD, then another option is to boot from a regular Alpine installation, and [[Burning_ISOs|manually mount the ISO image to {{Path|/media/cdrom}}]].}}

| | |
| === Determine the Device Name of the {{{1|Flash Medium}}} ===
| |
| Determine the name your computer uses for your {{{1|flash medium}}}. The following step is one way to do this.
| |
| # After inserting the {{{1|flash medium}}}, run the command:
| |
| #* {{Cmd|dmesg}}
| |
| #* At the end of this command you should see the name of your {{{1|flash medium}}}, likely starting with "sd". (For example: "sda").
| |
| #* The remainder of this document will assume that your {{{1|flash medium}}} is called /dev/sda
| |
| | |
| {{Warning|Be very careful about this. You do not want to mistakenly wipe your hard drive if it's on /dev/sda}}
| |
| | |
| === Format {{{1|Flash Medium}}} ===
| |
| Run fdisk (replacing sda with your {{{1|flash medium}}} name):
| |
| {{Cmd|fdisk /dev/sda}}
| |
| | |
| # (''Optional'') - Create new partition table with one FAT32 partition
| |
| #* '''d''' Delete all partitions (this may take a few steps)
| |
| #* '''n''' Create a new partition
| |
| #* '''p''' A primary partition
| |
| #* '''1''' Partition number 1
| |
| #** Use defaults for first and last cylinder (just press [Enter] twice).
| |
| #* '''t''' Change partition type
| |
| #* '''c''' Partition type (Win95 FAT32/LBA)
| |
| #Verify that the primary partition is bootable
| |
| #* '''p''' Print list of partitions
| |
| #* If there is no '*' next to the first partition, follow the next steps:
| |
| #** '''a''' <big>Make the partition bootable (set boot flag)</big>
| |
| #** '''1''' Partition number 1
| |
| #'''w''' Write your changes to the device

| === Add Alpine Linux to the {{{1|Flash Medium}}} ===
| |
| To boot from your {{{1|flash medium}}} you need to copy the contents of the CDROM to the {{{1|flash medium}}} and make it bootable. Those two operations can be automated with the [[setup-bootable]] tool or can be done manually.
| |
| | |
| {{Note|If the following commands fail due to 'No such file or directory', you may have to remove and reinsert the {{{1|flash medium}}}, or even reboot, to get /dev/sda1 to appear}}
| |
| | |
| ==== Automated ====
| |
| {{Tip|If using Alpine Linux 1.10.4 or newer, you can use this section to complete the install. Otherwise, follow the Manual steps below.}}
| |
| # Run the [[setup-bootable]] script to add Alpine Linux to the {{{1|flash medium}}} and make it bootable (replacing sda with your {{{1|flash medium}}} name):
| |
| #: {{Cmd|setup-bootable /media/cdrom /dev/sda1}}
| |
| {{Note|The target partition has to be formatted. Use the <code>mkdosfs</code> command from the Manual steps below if needed.}}
| |
| {{Warning|If you are installing to a USB Stick, the <code>setup-bootable</code> script will not use <code>usbdisk</code> in the {{Path|syslinux.cfg}} file. You should modify it to say <code>usbdisk</code> as [[#Wrong_Device_Name|described below]], or you will face possible problems booting and definite problems with the package cache.}}
| |
| | |
| ==== Manual ====
| |
| # (''Optional'') - If you created a new partition above, format the {{{1|flash medium}}} with a FAT32 filesystem (replacing sda with your {{{1|flash medium}}} name):
| |
| #: {{Cmd|apk add dosfstools<BR>mkdosfs -F32 /dev/sda1}}
| |
| # Install syslinux and MBR (replacing sda with your {{{1|flash medium}}} name):
| |
| #: {{Cmd|{{{|apk add syslinux<BR>dd if=/usr/share/syslinux/mbr.bin of=/dev/sda}}}<BR>syslinux /dev/sda1}}
| |
| #Copy the files to the {{{1|flash medium}}} (replacing sda with your {{{1|flash medium}}} name):
| |
| #: {{Cmd|<nowiki>mkdir -p /media/sda1
| |
| mount -t vfat /dev/sda1 /media/sda1
| |
| cd /media/cdrom
| |
| cp -a .alpine-release * /media/sda1/
| |
| umount /media/sda1</nowiki>}}
| |
| | |
| == Troubleshooting ==
| |
| === Wrong Device Name ===
| |
| If you cannot boot from the {{{1|flash medium}}} and you see something like:
| |
| Mounting boot media failed.
| |
| initramfs emergency recovery shell launched. Type 'exit' to continue boot
| |
| then it is likely that the device name in syslinux.cfg is wrong. You should replace the device name in the syslinux.cfg line:
| |
| append initrd=/boot/grsec.gz alpine_dev='''usbdisk''':vfat modules=loop,cramfs,sd-mod,usb-storage quiet
| |
| with the proper device name.
| |
| * For boot from USB, the device name should be 'usbdisk' (as shown above)
| |
| * For other options, you can run '''cat /proc/partitions''' to see the available disks (i.e. 'sda' or 'sdb')
| |
| | |
| === Non-FAT32 Filesystems ===
| |
| When your {{{1|flash medium}}} is formatted with a filesystem other than FAT32, you might have to specify the necessary filesystem modules in the boot parameters.
| |
| | |
| To do so, mount the {{{1|flash medium}}} and change the syslinux.cfg file line from
| |
| append initrd=/boot/grsec.gz alpine_dev=usbdisk:vfat modules=loop,cramfs,sd-mod,usb-storage quiet
| |
| to
| |
| append initrd=/boot/grsec.gz alpine_dev=usbdisk:vfat modules=loop,cramfs,sd-mod,usb-storage''',ext3''' quiet
| |
| in the case of an ext3 formatted partition. A similar procedure might apply to other filesystems (if they are supported by syslinux and the Alpine Linux kernel).
