Question: ISA adapter with Ricoh chipset

Just putting a system together (RH6.2) and added a PCMCIA ISAbus adapter (with a RICOH RF5C?96 chipset) to fit a wireless pcmcia card. Everytime I launch pcmcia (/etc/rc.d/init.d/pcmcia start) I get: kernel: Linux PCMCIA Card Services 3.1.8 kernel: kernel build: 2.2.14-5.0 #1 Tue Mar 7 20:35:25 EST 2000 kernel: options: [pci] [cardbus] [apm] kernel: Intel PCIC probe: kernel: Ricoh RF5C296/396 ISA-to-PCMCIA at port 0x3e0 ofs 0x00, 1 socket kernel: host opts [0]: none kernel: ISA irqs (default) = 3,7,9,10,11,12,15 polling interval = 1000 ms cardmgr[5248]: starting, version is 3.1.8 and the entire system crashes. Note, no pcmcia card is plugged in at this moment. finally I figured out that my motherboard has a built-in LPT2 port, which to my knowledge is using the same base io-address 0x3e0, as the pcmcia ISA adapter. unfortunately the motherboard does not allow to turn the lpt2 port :-((. From what I've learned so far the ricoh PCMCIA chipset allows memory remapping. Is this supported with the current pcmcia package? If so, how would I configure it? mattes

Sounds like an IO port scan failure Re: Question: ISA adapter with Ricoh chipset (Matthias Kattanek) Date: 2000, Apr 21 From: David Hinds <dhinds@pcmcia.sourceforge.org>

You have a parallel port at 0x3e0? That would be quite odd: this is not a standard location for a parallel port. Also I don't think that can be the problem, because it should have interfered with correct identification of the Ricoh chip if it were true. The PCMCIA-HOWTO has a section about diagnosing startup crashes. Your messages show that the interrupt probe succeeded, but you're getting stuck when cardmgr loads, even with no card inserted. That matches the HOWTO description of an IO port scan failure (section 3.4). Edit the IO port windows in /etc/pcmcia/config.opts. I'd probably try deleting the windows one by one until the lock-up goes away. Another option would be to try recompiling PCMCIA with "PnP BIOS support" switched on, which may do a better job of automatically figuring out IO port resources used by other system devices. The memory mapping in the Ricoh bridge is for mapping PCMCIA cards into the host address space. It doesn't allow you to change the IO address of the Ricoh bridge itself. I don't think you can change that. -- Dave
