Maybe I should write a FAQ or HOWTO on these damned cards. They're popping
up *EVERYWHERE!* Why can't these companies include an NCR3c400 or
something?!? *sigh*

Okay, this one's gonna be long, you weirdos who like to fsck with this
stuff, pay attention. ;)
First off; these cards aren't true AHA-1520B's or C's or E's or whatever.
They're actually single-chippers. The cards I work with the most are made
by P.E. Logic, the "PEL-1600." It's an ISA card, with a DB25 external,
50pin internal. Jumpers are behind the internal connector. It has an 8
switch DIP on the back right corner for setting port, IRQ, Termination,
and enabling or disabling 'PORT' which I haven't figured out yet.
First off; you've got the right driver. You DO use the AHA152x driver.
Next; Somebody should probably add this to Documentation. Maybe I'll do
it if I can find the time. This is the hard part.
[kernel@bob scsi]# wpe Makefile
<snip of menus and stuff :>
You'll see a line like this:
AHA152X = -DDEBUG_AHA152X -DAUTOCONF
Do this:
#AHA152X = -DDEBUG_AHA152X -DAUTOCONF
AHA152X = -DDEBUG_AHA152X -DSKIP_BIOSTEST -DSETUP0="{0x140,11,7,1,1,0,120,1}"
Where the paramters inside the brackets are as follows:
IO Address, IRQ, SCSI ID, Reconnect, Parity, Synchronous, Delay, Extended
Translation
1 = Yes, 0 = No. Not that hard. :)
Next...
[kernel@bob scsi]# wpe /etc/lilo.conf
Drop this in:
image=/vmlinuz
label=linux
root=/dev/hdb1
read-only
vga=ask
append="aha152x=0x140,11,7,1,1,0,120,1"
Modify to match the way you want yer kernel, and to match the Makefile.
You can't do one or the other; you MUST do both. This is a (bug/feature)
in the driver.
As always, YMMV. If you ask me, you're better off getting a new SCSI card.
I just picked up a Tekram DC390F (NCR3c875 based, FYI), should be here
today, so we'll see how it works. :)
If anybody has any comments, or an easier way to do this, I'm listening. I
*HATE* having to do all that for some $5 ISA SCSI card. };P
