Create a Bootable Compact Flash

Installing Alpine on Compact Flash (CF)

This document applies to Alpine Linux 1.9.0 or later, and results in a run-from-ram style installation.

Requirements

In order to follow this document, you will need:

• Alpine Linux CD-ROM (Download a .iso file containing an Alpine release.)
• Computer with CF card reader
• CF card
  • Note: Some CF card readers have problems with the faster CF cards on the market. If you experience problems booting the CF card even after checking BIOS settings, you may need to use an older card.

If you already have a running Linux system (Alpine Linux 1.8.x, Debian, Gentoo, RedHat, etc.), log in as root, insert the Alpine Linux CD-ROM into the running Linux computer, and skip the next section.

Boot Alpine Linux CD-ROM

1. Insert the Alpine Linux CD into a computer.
2. Boot the computer from the Alpine Linux CD-ROM.
   • This step may require changes to the BIOS settings to select booting from CD.
3. Login with the username root. No password is needed.

Setup bootable media

Tip: If using Alpine 1.10.4 or newer, you can use this section to complete all setup, then skip to the See Also section to continue with your setup. If not, please proceed to the next section now.

1. Insert the removable CF Card into the computer.
2. Determine the name your computer uses for your CF Card. The following step is one way to do this.
   • After inserting the CF Card, run the command:

   • dmesg

   • At the end of this command you should see the name of your CF Card, likely starting with "sd". (For example: "sda").
   • The remainder of this document will assume that your CF Card is called /dev/sda

1. Mount the Alpine Linux CD-ROM, and copy the files to the flash medium

   • mount /media/cdrom

1. Run the setup-bootable script to install Alpine

   • setup-bootable /media/cdrom /dev/sda

Tip: You can now skip to the See Also section.

Modify syslinux.cfg for Compact Flash Card

Most cards are mounted as IDE drives (sda1) and not as usbdisks. Therefore, edit /media/sda1/syslinux.cfg and replace usbdisk with sda1

Also, many CF card readers don't support DMA correctly, so you may need to add nodma to the append line.

Alpine Linux has some special applications that helps you to use it in the way you want.
Some of the first scripts you are suggested to use is:

• setup-alpine (Configures all basic things on your Alpine Linux)
• setup-acf (was named setup-webconf before Alpine 1.9 beta 4) (Configures ACF (webconfiguration) so you can manage your box through https)

Note: Just type any of the above commands on your console and hit Enter to execute the script.
