Device name endianness issue in AHCI mode

Description
In BootManager, the vendor/model name of the SATA disk appears in the opposite endianness, when having set the BIOS setting "SATA AHCI MODE" : AHCI. (scsi)
When set to IDE, it shows as expected. See screenshots.
Haiku nightly gcc2hybrid hrev42636.
(Additionally the DVD drive appears in BootManager in AHCI/scsi mode, but is filtered out(?) in IDE/atapi mode. I'm guessing the latter is the expected behavior also for AHCI/scsi.)

I've got the same problem:

Fixed in hrev44924. Note that the SCSI inquiry block is way too small to fit in all of the ATA data. We do the same thing in AHCI as in ATA though, so the resulting string should be the same.

In hrev44930 there is a minor problem with spaces:

Replying to diver:
In hrev44930 there is a minor problem with spaces:
No there really isn't. As mentioned in the commit message, there is just too little space in the SCSI structure to hold the original model name. Hence as much as possible is put in the vendor and product ident fields, these are 8 and 16 bytes respectively. The name that is displayed is a concatenation of these fields with a space. For actual SCSI disks this would be correct, for ATA behind SCSI this is as close as it gets without changing the underlying way the name is retrieved. In any case that'd be an enhancement ticket.
Hi Jonas,
the AHCI bus manager swaps words before returning the inquiry here. You could try to do the same for the scsi bus manager probably here.
Bye,
