VirtualBox also ships with a set of drivers that improve running OS/2 in a virtual machine. Due to restrictions of OS/2 itself, this variant of the Guest Additions has a limited feature set; see Chapterá13, Known issues for details.

The OS/2 Guest Additions are provided on the same ISO CD-ROM as those for the other platforms. As a result, mount the ISO in OS/2 as described previously. The OS/2 Guest Additions are located in the directory \32bit\OS2. We do not provide an automatic installer at this time. In that directory, a file called readme.txt describes how to install the OS/2 Guest Additions manually.
