Nubus/PDS (Processor Direct Slot) Devices Definitions
Note: Because of the ability for the Nubus/PDS boards to provide many not only
new but duplicate services (such as additional serial ports, another SCSI
Bus, etc.) there may be additional information here regarding the
capabilities of your machine that does not appear in other report
categories.
[Text] = Item only exists under given circumstance
General:
Nubus and PDS boards communicate their purpose and functions through
a declaration ROM mounted on the board. If there is a declaration ROM,
the board can be reported on, otherwise the Slot Manager is unaware that
a board is in the slot. PDS slots are different from Nubus slots in many
senses. Other than the several different physical and electrical
specifications that PDS slots possess, PDS boards are somewhat less likely
to have a declaration ROM than Nubus boards. If a declaration ROM is
present, either type board is reported by slot after the physical slot
counts below.
Nubus/PDS slots come in two forms, physical and built-in. An example
of a built-in slot is the video connector provided on most newer machines.
Physical slots are those into which a board can actually be inserted.
• Total Physical PDS Slots Present = Total number of physical PDS slots
in the machine
• Total Physical Nubus Slots Present = Total number of physical Nubus
in the machine
========================================
• Nubus/PDS Slot# = This represents the slot number in hex as seen by the Slot
Manager. Built-in slots range in number from $0-$E while physical slots
range from $9-$E. These numbers are machine type dependent. Only
physical slots with boards and built-in slots with connected devices are
reported. In certain cases, e.g. the LC, a built-in slot with no connected
device may appear
◊ Pseudo Nubus Slot# = This number represents the physical location of the
Nubus slot containing the board, counting from the closest parallel side of
the machine [Nubus Slot]
◊ Board Name = Name of the board [Present In Board ROM]
◊ Board ID = Identification number of the board as assigned by manufacturer
[Present In Board ROM]
◊ Vendor ID = Name of manufacturer [Present In Board ROM]
◊ Serial# = Board serial number [Present In Board ROM]
◊ Revision Level = Revision level of the board [Present In Board ROM]
◊ Part# = Part number assigned by the manufacturer [Present In Board ROM]
◊ Date = Date of manufacture or revision [Present In Board ROM]
◊ Functional Resources: Following this heading is a listing of those functions
which are currently available on the board. Some boards, e.g. SCSI,
may support more than one device or device type. If you see a number
next to Category or Type without a (name) next to it, please send us
the numbers and any information which you may know regarding the
function of the board. This information will then be used to update the
category and type names
+ Device SResource Name = Name of function from board’s point of view
- Device Category = Category number and (category name) if known
- Device Type = Device number and (type name) if known. If it is a video
device, more information is available under Monitors, referenced by the
Nubus/PDS slot number
- Device Software Interface Type = Format of the driver’s interface
- Device Hardware ID = Identifies the supported hardware
- Device SResource ID = Number, in hex, of the SResource which
describes this function
- Driver Number = Number of the driver which controls this device.
Refer to the Driver list
