extra_sockets parameter set to 1. This should not be necessary for detection of
PCI−to−PCMCIA or PCI−to−CardBus bridges.
Here are some timing settings for specific systems:
• On the ARM Pentium−90 or Midwest Micro Soundbook Plus, use ``freq_bypass=1
cmd_time=8''.
• On a Midwest Micro Soundbook Elite, use ``cmd_time=12''.
• On a Gateway Liberty, try ``cmd_time=16''.
• On a Samsung SENS 810, use ``fast_pci=1''.
2.4 System resource settings
Card Services should automatically avoid allocating IO ports and interrupts already in use by other standard
devices. It will also attempt to detect conflicts with unknown devices, but this is not completely reliable. In
some cases, you may need to explicitly exclude resources for a device in /etc/pcmcia/config.opts.
Here are some resource settings for specific laptop types. View this list with suspicion: it may give useful
hints for solving problems, but it is inevitably out of date and certainly contains mistakes. Corrections and
additions are welcome.
• On the AMS SoundPro, exclude irq 10.
• On some AMS TravelPro 5300 models, use memory 0xc8000−0xcffff.
