Up to now "select without attention" was handled the same way as "select with attention". According to NCR53C9X documentation, select without ATN sends the CDB (Command Descriptor Block) directly, whereas select with ATN sends one message phase byte followed by 6, 10, or 12 command phase bytes. This one byte was shifting CDB and producing invalid commands. After fixing this bug scsi probe looks like this:
ok probe-scsi
Target 0
Unit 0 Disk
Target 2
Unit 0 Removable Read Only device
ok
It still doesn't show all the target properties, but it doesn't matter. The next stop is booting.
