Does Haiku now, or in the future, planning to support parallel SCSI or SAS? Back in the BeOS days I was able to use my Adapttec U160 SCSI controller on r5 by borrowing the aic78xx driver from Dano.
In answer to my own question, “No, Haiku does not have SCSI support at this time”.
I dug out my old SCSI controller card and Seagate drive and tried to install Haiku, only to get a kernel panic during the boot sequence.
However, Dano and Zeta both installed without issue.
