Download the ramdisk.gz image from the link above and copy it to an ATA flash card. Also copy onto the card, the kernel zImage file for the kernel you want to use.

For systems such as the BitsyXb, BitsyG5, TurboXb, Sphere, VGX, VIX, and Portal, which use the u-boot bootloader, a set of u-boot configuration files is needed. See this topic for all the available files, download the appropriate files and copy them to the card. You will need at a minimum start.txt, ramdisk root_config.txt, and a tty_config.txt file for your system. A hw_config.txt file for your system's frame buffer is recommended for best performace of the video demonstration programs included in this distribution.

For PXA systems such as the BitsyX, AGX, and GCX, which do not use the u-boot bootloader, a kernel command line is required to direct the kernel to mount this file system during start up. Download a cmdline.txt file as shown below and copy it to the card, then create a file named ProgramFlash.ads! on the card. A register.txt file is recommended for best performace of the video demonstration programs included in this distribution. Download the register.txt file for your system's frame buffer as shown below and copy it to the card.

On your ADS system, set the first dip switch to ON (Flash Update Mode) make sure that the DIP switches on your system are NOT set to 'secure mode' (secure mode prevents booting from PCMCIA/compact flash).

Now insert the card, and boot your system. The kernel and ramdisk root file system will be loaded from the card, and Linux will start. Booting from the card this way allows you to try different kernels and ramdisks until you satisfied - without having to erase and reprogram on-flash memory.

If and when you want to install the kernel and ramdisk and boot from on-board flash, instead of the ATA flash card, follow these instructions: For boards using the u-boot bootloader, download the ramdisk_from_flash root_config.txt file and reboot the system. For boards not using the u-boot bootloader, create a file named ProgramFlash.ads! on the card. The bootloader will erase everything in on-board flash (except the bootloader itself) and program (copy) the images on the ATA card to on-board flash. The kernel and ramdisk will be loaded from on-board flash and the ramdisk will be uncompressed and mounted when Linux starts.

Remove the ATA flash card to prevent an unnecessary erase/reprogramming of on-board flash the next time you reboot. See the bootloader manual for more information on the dip switch settings and boot options.

On the BitsyX, use this cmdline.txt.

On AGX, GCX and VGX, use this cmdline.txt.

MD5SUMS provides MD5 checksums for all files in this release.

This ramdisk root file system is derived from Debian and supersedes our previous 2007-05-07 release. This release is based on the stable Debian 4.0r1 release.
