Hi,
A few questions about how modules.conf works...
I'm getting a laptop for linux. It's a Toshiba Satellite 490CDT. PII 233
era. It has a build in opl3-sa3 sound card. The card's not PNP but rather
is configured (lots of memory address, and interrupt, and a couple of DMAs)
through bios. I've installed Mandrake 8.2 (kernel 4.2.18) on it.
Looking around I found that one method of getting a non-pnp sound card would
be to add a couple of lines to /etc/modules.conf. I've added...
alias sound-slot-0 opl3sa2
options opl3sa2 io=0x558 mss_io=0x550 mpu_io=0x330 irq=5 dma=1 dma=0
options opl3 io=0x388
With these lines - but not without them - the following appears toward the
tail of dmesg....
op3sa2: No PnP cards found
op3sa2: Search for a card at 0x1368
op3sa2: chipset version = 0x5
op3sa2: Found OPL3-SA3 (YMF715E or YMF719E)
op3sa2: Control I/O port 0x558 not free
op3sa2: There was a problem probing one of the ISA PNP cards, continuing
.......... the last two lines repeat twice .............
The sound card now works fine.
Questions:
Does the first line - the alias - prompt the module to look for pnp devices?
Why did it look for a card at 0x1368?!
Why did it look for the card at 0x558 three - or perhaps four - times?
Cheers,
Gord
