Trying to load module "aha1542
" does not work; no
SCSI host adapter is found.
Autoprobing only searches at addresses 0x330
and
0x334
("I/O Portaddress");
(have a look at the driver source code
/usr/src/linux/drivers/scsi/aha1542.c
).
If possible set one of the addresses mentioned above.
0x334
should
be fine if you are using a sound catrd.
If you have to use a different address try a monolithic kernel image with build in aha1542 support and enter a the LILO prompt:
LILO: linux aha1542=0x300
You can set these settings for further use in /etc/lilo.conf
append
line (please check the chapter of the manual about
LILO).
SDB-Artikel kfr_26.html.
If you are just installing the system you should use one of the boot images
supporting AHA1542. YouŽll find these images on CD1 in /disks
.
The creation of bootable disks with one of these images is described in
your manual, too.
If you compile your own kernel make sure to include support for
"Adaptec AHA1542
" (not as modul).
If you already have a running system and want to add the adapter card try to load the modul running
modprobe -v aha1542=0x300,15,7,1,1Adjust the parameters according to your hardware. The meanings of the parameters can be derived from the kernel sources :
/usr/src/linux/drivers/scsi/aha1542.c ... /* * LILO params: aha1542=[,,[,]] * * Where: is any of the valid AHA addresses: * 0x130, 0x134, 0x230, 0x234, 0x330, 0x334 * is the time (in microsecs) that AHA spends on the AT-bus * when transferring data. 1542A power-on default is 11us, * valid values are in range: 2..15 (decimal) * is the time that AHA spends OFF THE BUS after while * it is transferring data (not to monopolize the bus). * Power-on default is 4us, valid range: 1..64 microseconds. * Default is jumper selected (1542A: on the J1), * but experimenter can alter it with this. * Valid values: 5, 6, 7, 8, 10 (MB/s) * Factory default is 5 MB/s. */
