The SATA AHCI disk controller driver has been updated (9/20/2012) to version 1.24, although this is not an officially released version. It appears the next version on the eComStation Betazone
(for Software Subscription customers only) will also include better
os2dump support. The GPL source code (based on the Linux kernel) is
available from the AHCI project site, and a build from earlier code (9/16/2011) is publicly available.
