Hi,
I'm to install OpenBSD on an old Thinkpad, but I first need to dump
the curr hdd contents, using the install cd, to a large CF card, via
a PCMCIA adapter.
The pcmcia stuff is correctly detected by the kernel, but wdc_pcmcia
only appears to access the device in pcmcia mode (1-sector PIO),
killing performance. I'm sure the CF card supports ATA mode and DMA
as it's been used in the past as an ATA device through (guess what)
an appropriate adapter.
Inspection of the source code appears to reveal that there's a rather
strict separation between wdc_pcmcia and (the presumably needed)
wdc_isa. Is this true?
Can I somehow safely force wdc_isa to attach instead of wdc_pcmcia, or
otherwise have OpenBSD have operate the card in ATA mode?
dmesg output has to be routed through the 10-finger interface and will
thus be provided only on request :)
Please understand that the situation is complicated by not having a
running OpenBSD install around (the whole point is to fix that!).
Nevertheless, I'm of course willing to try 'patches' in the form of
i386 CD boot images. If truly needed I can of course dump the hdd
contents through a certain terminal emulator developed in Helsinki,
but I'm sure you understand that I'd rather avoid that...
Thanks in advance for any insight or effort,
--schaafuit.
P.S.: Since I'm not currently subscribed to this mailing list, courtesy
copies are very much appreciated. Also apologies for any broken
spacing, this is currently beyond my control and will be fixed in
the future.
