BusLogic driver with spurious logical units

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Using Virtualbox (6.1.18 r142142) with Buslogic & IDE, I booted a fedora
33 (5.10.15-200.fc33.x86_64) server ISO and I find *many* targets with
size 512 bytes which is incorrect.  To get another data point, I used
same VM and a NetBSD 9.1 ISO and that booted with the expected
configuration.  Although, it still could be a VM hardware model issue.

Expected:
1 80GB IDE disk & CDROM
1 2GB SCSI buslogic attached disk

Found:
1 80GB IDE disk & CDROM
120 512-byte SCSI disks
