Message:

OS2AHCI Version 1.19
====================

• Added retry counters to all commands (IORBs) in order to prevent infinite retry loops. This was necessary because Virtualbox 4.x doesn't seem to set the "current command index" in specific ATAPI error situations, causing the failing command to be retried indefinitely instead of asking for a sense buffer

• Minor changes to debug logging
