| − | The CM-X270 platform support was merged into mainline kernel starting from version 2.6.24. There are still some features that are not present in mainline kernel. Most of these features are available in preliminary release of [http://www.compulab.co.il/mediawiki/files/Linux/x270cm/linux-2.6.24-cm-x270.tar.gz Linux kernel 2.6.24 for CM-X270] (source code only).

| − | It is possible to use mainline Linux kernel 2.6.24 on CM-X270 "as is". Just keep in mind that the on-board NAND flash can be accessed only using [[Linux MTD drivers on CM-X270|MTD drivers]] and the serial ports map to different {{parameter|ttys}} on L and W variants as summarized in the below table:
