Troubleshoot the Card
Occasionally, your system may need to be altered to allow the PCMK card to work
properly. Documented below are some tips and suggestions for helping you set up
the RSIPCMK driver and the PCMK card successfully.
Hearing Multiple Tones
If you insert multiple PC cards, you may hear more than one tonal notification per
card. The Windows 95/98 operating system detects devices during the power up
process, and adjusts the device resources accordingly. This results in sounding
multiple tones. When the system changes settings, for example removing a card,
the tones will sound again for each change.
Memory Manager Conflicts
If you load the EMM386.EXE file, through the CONFIG.SYS file, you may interfere
with the RSIPCMK driver’s ability to map the PCMK card into memory. If you are
unsure if you are loading the EMM386.EXE file, perform the following steps.
1. Access the Run dialog by choosing Start ⇒Run.
2. Type sysedit in the Open field.
3. Click OK.
This starts an editor that lets you view and modify your CONFIG.SYS file.
4. Access the CONFIG.SYS file.
5. Scroll through the file to see if the EMM386.EXE file is contained in any of
the lines. You can use the Find option within the Search menu to locate
every instance of EMM386.
