David, thank you for your kind reply and my apologies for delay in response. You wrote: >First, the interrupt problem: that one is my mistake.

I've built the latest kernel (2.3.51) and got the same wrong numbering of busses: kernel: Linux PCMCIA Card Services 3.1.13 kernel: kernel build: 2.3.51 #11 Sun Mar 12 00:15:51 JST 2000 [snip] kernel: TI 1130 PCI-to-CardBus at slot 00:13, mem 0x80803000 kernel: host opts : [pci only] [pci irq 22] [lat 32/176] [bus 1/2] kernel: host opts : [pci only] [pci irq 23] [lat 32/176] [bus 3/4] kernel: PCI card interrupts, polling interval = 1000 ms cardmgr: starting, version is 3.1.13 [snip] kernel: cs: no valid ROM images found! >However, you say you have the same "no valid ROM images" problem with >2.2.15pre9 and later kernels, and that makes less sense to me.

I found that this "no valid ROM images" problem with 2.2.15pre* kernel is dependent on whether or not I used some patches applied to drivers/pci/pci.c and arch/ppc/kernel/pmac_pci.c, which were originally written by Ryuichi Oikawa for the purpose of using 32-bit cardbus cards as PCI cards under linuxppc. You can check the contents of the patches from the URL below: http://www.rr.iij4u.or.jp/~roikawa/others.html (written in Japanese) I'd incidentally applied these patches to my linux-2.2.15pre7 but not to others. Now I've built the latest pre14 kernel and applied the same patches to it. Then the 3.1.13 beta pcmcia-cs was well working with my 32-bit cardbus LAN card. Unfortunately it appears that these patches can not be applied to 2.3.* kernels. My great apologies to you for taking your time. p.s. To PB users: To use the above patched kernel with pcmcia-cs and 32-bit cards, I used OF (Open Firmware) booting into the kernel. To use booting into this kernel via BootX under MacOS, the pcmcia service should be disabled.
