Stealth Mode - IBM Turbo 16/4 Token-Ring PC Card 2 User Manual

Stealth Mode

The device drivers for Turbo 16/4 Token-Ring PC Card 2 are fully
backward-compatible with all of the previous versions of IBM Token-Ring Credit
Cards, however there have been improvements in the hardware with the
introduction of the Turbo PC Cards. That new hardware feature is referred to as
Stealth Mode and can be used in the Turbo 16/4 Token-Ring PC Card 2 to remove
power from the card by removing only the cable. The operating system will not
sense the presence of the card in the slot with the cable detached.
With previous IBM Token-Ring Credit Cards, with the exception of the IBM Turbo
16/4 Token-Ring PC Card, the card and cable had to be removed from the
computer to remove power to the slot and the detection of the adapter from the
operating system.
When removing the cable from the PC Card while the system is running or
connected to the network or both, stop the PC Card before you remove the cable or
card, just as you normally would when removing any adapter from the system.
Note: If the cable is disconnected at boot time under a Plug and Play operating
2

system, the operating system will not be aware of the PC Card's presence
and will not try to load the device drivers for the PC Card. However, under
an operating system which is not Plug and Play compliant, the operating
system will try to load the PC card device drivers anyway and as a result the
operating system will generate an error message referring to the adapter or
the device drivers or both.
