The IBM PalmTop PC110Using PS2.EXE: Hardware Configuration |
Hardware Configuration |
||
Values: 1 or 3
Type: basic
Selects the DMA channel to be used by the ESS488 Audiodrive.
Values: 5 or 10 or Disable
Type: basic
Selects the interrupt to be used by the ESS488 Audiodrive. Disable will
disable the audio device.
Values: 15E0 or 25E0 or
35E0
Type: basic
Selects the I/O address to be used by the touch pad.
Values: 5 or 10 or Disable
Type: basic
Selects the interrupt to be used by the touch pad. Disable will disable the
touch pad.
_@COMB
Values: RS232 or IRDa or
MIDI or ASK
Type: advanced
Unknown. I strongly suspect it is to do with assigning hardware resources, such as I/O addresses and IRQ level, and the fact that you may not be able to have all of these devices active at once. However, the options here differ from the Serial section of EasySetup, in that there is no mention of the internal modem or the PCMCIA modem.
If anyone has more information on this particular command, please let me know.
Values: 1 or 2 or
Disable
Type: basic
Selects the com port to be used by the internal modem. Disable will disable
the internal modem. Note that only com1 and com2 can be chosen.
Values: 1 or 2 or
Disable
Type: basic
Selects the com port to be used by the infra-red port. Disable will disable
the infra-red port. Note that only com1 and com2 can be chosen.
Values: 1 or 2 or
Disable
Type: basic
Selects the com port to be used by the PCMCIA modem. Disable will disable the
PCMCIA modem - this applies to the special BIOS tricks used to
directly access PCMCIA devices - the PCMCIA modem will still be accessible provided PCMCIA
device drivers are loaded. Note that only com1 and com2 can be chosen.
Values: 1 or 2 or
Disable
Type: basic
Selects the com port to be used by the serial port on the port replicator. Disable
will disable the serial port. Note that only com1 and com2 can be chosen.
Values: Auto or Both
Type: advanced
Alters the way the PC110 reacts to an external keyboard. If set to Auto, the
PC110 will use the external keyboard if detected at boot up or upon resuming from suspend
mode, and disable the internal keyboard. If set to Both, the PC110 will take
input from either keyboard - but remember to connect the external keyboard whilst the
PC110 is in suspend mode, then resume it, so that it is detected.
Values: BI or UNI or
ECP or EPP
Type: advanced
Configures the operation of the parallel port. Default is bidirectional (BI). ECP
and EPP do not appear to work - certainly my parallel port ZIP drive drivers do
not detect the port when set to EPP or ECP.
Values: Primary or Secondary
Type: advanced
Controls the ordering of the IDE controllers present in the machine. Only has meaning when a PCMCIA ATA storage card is added to the PC110.
When a PCMCIA ATA device is present in the PC110, there are effectively
two IDE controllers (two IDE channels) present - one to control the 4MB Flash drive, and
any CompactFlash cards inserted, and the other within the PCMCIA device itself,
controlling that device. This command allows you to change how these channels are seen by
the BIOS, and assigned resources:
| Flash controller | PCMCIA ATA controller | |
| PS2 _@ATA Primary | not configured | I/O 1F0h, IRQ 14 |
| PS2 _@ATA Secondary | I/O 1F0h, IRQ 14 | I/O 170h, IRQ 15 |
Note that if Primary has been selected and there is no PCMCIA ATA device present,
the Flash controller will again be visible at I/O 1F0h, IRQ 14.
Default value is Secondary.
Values: Enable or Disable
Type: advanced
Controls the behaviour of the floppy disk drive (controller). I do not know what it defaults to, and have seen no obvious changes in behaviour by using either value.
If anyone has more information on this particular command, please let me know.
Values: Enable or Disable
Type: advanced
Affects support for 3V PCMCIA devices. Defaults to Disable, so the PC110 will
not support a 3V PCMCIA device unless you issue this command to enable such support.
Values: Enable or Disable
Type: advanced
Controls the status of the PCMCIA controller. If set to Disable, the PCMCIA controller will not be seen by your operating system. However, the BIOS remapping of PCMCIA devices (ATA storage, modems, token-ring cards) will still occur.
Default setting is Enable.
Values: 4Mbps or 16Mbps
Type: advanced
Configures the PC110 RIPL function for either a 4Mbps or 16Mbps PCMCIA token ring card,
as appropriate. Only useful if you have such a card installed and have selected Network
as one of your start up options in EasySetup, and you have a RIPL server located on
your network with a suitable boot image for the PC110.
Values: [ OR or AND
or XOR ] [ xxH [ =yyH
] ] (where xx is a two-digit hex address, and yy is
the two-digit hex data)
Type: advanced
Displays and manipulates the CMOS settings. USE WITH EXTREME CARE.
This appears to be a left over from the development of the machine. It allows developers to display and manipulate CMOS settings, to verify the state information which they contain.
Without any parameters, PS2 _@CMOS will display the full 256 bytes of CMOS data. Anyone know what these relate to? I have started investigating this, but do not have any definitive results yet.
If you are tempted to tinker with this command, read If it all
goes wrong... for tips on resetting the state of the PC110.
Values: Enable or Disable
Type: advanced
Unknown. I suspect it may affect hardware configuration, or be a debugging option left in by the developers.
If anyone has more information on this particular command, please let me know.
