read the microchannel configuration registers
/etc/slot [ -a adid ]
[ -fadnamesfile ]
[ -s slot ]
The slot command displays the contents of the configuration POS
registers on a microchannel architecture machine, and names the adapter
cards currently configured in each slot.
For each of the eight adapter slots, slot shows the slot number,
the unique adapter id (four digits in hexadecimal from registers
0x100 and 0x101), the contents of the remaining six POS registers
(two hexadecimal digits each), followed by the adapter card name.
The default slot display looks similar to this:
Slot AdID Regs 0x102-0x107 Adapter Name
1 ---- -- -- -- -- -- -- Empty Slot
2 0f1f 01 3b f7 31 ff ff Adaptec 1640 SCSI Host Adapter
3 ---- -- -- -- -- -- -- Empty Slot
4 6bbc 81 00 00 85 ff ff Apricot Synchronous Communications Adapter
5 6bba 81 00 00 b6 ff ff Apricot Ethernet Controller
6 dfbf 05 02 ff ff ff ff IBM 6157 Streaming Tape
7 ---- -- -- -- -- -- -- Empty Slot
8 ---- -- -- -- -- -- -- Empty Slot
The available slot options select a particular adapter id,
a particular slot, or select an alternative names file.
Shows only the information for those slots in which
an adapter of that id is configured (no display if no
such adapter). adid should be specified in hexadecimal.
For example, /etc/slot -a dfbf shows only those slots which contain
an IBM 6157 Streaming Tape adapter card.
The text displayed by /etc/slot is normally read from the
file /etc/default/slot. This option redirects it to read
from an alternative file adnamesfile. For example,
/etc/slot -f /dev/null
shows only the register contents of occupied slots, without
the accompanying text, which can be useful when processing
the output automatically in a shell script.
Shows only the information for that slot (no display
if that slot is empty). For example, /etc/slot -s 6
shows only the information for slot 6.
Returns 0 upon successful completion. Returns 1 if incorrectly invoked,
if the machine is not a microchannel architecture machine
(/dev/mcapos unreadable), if the selected
adapter id is not found, or if the selected slot is empty.
If run on a machine which does not have the microchannel architecture,
slot reports ``not an MCA machine'' and exits returns 1.
If an adapter id is not listed in /etc/default/slot, slot
reports ``Unknown card'' for that slot. The System Administrator should add
an entry for that adapter id to /etc/default/slot.
slot reports what adapter is configured in which slot. No
indication is given as to whether that adapter is working, nor whether
that adapter is connected to working hardware. No indication is
given as to whether the current SCO OpenServer kernel
supports that adapter, nor whether a driver for that adapter is
available for SCO OpenServer.
slot cannot be used to change the configuration shown. To change
the configuration, use the setup disk supplied with your machine. Consult
the hardware documentation supplied with your machine for details
concerning the use of the setup disk.
This file contains the headers, footers and adapter names
shown by the slot utility. The text in this file may be
translated, or extended as new adapters are announced.
The display of header lines, empty slots, and footers
may be suppressed by omitting their text.
The slot utility reads the 64 bytes of MCA POS
register configuration information from this device.
