  The base address of 0x330 may cause a problem with some sound cards,
as mpu often uses that as a default. But, it should not keep you from
being able to install. My SCSI came set with 0x130 as the default. Irq
11 is pretty standard; I run my 1542 there.
   I bought this machine at a used computer Meet and just wanted to
see if RH 7 would install. I remember having problems getting past the
loading Adaptec 154x driver from the driver.img floppy section. I
tried various combinations of:

          aha1542=0x130
          aha154x=0x130
          aha1542=0x130,11
          aha1542=0x130 irq=11
          etc.
  I'm not sure, but if I remember correctly, you may have to
specifically select the "don't probe" for card option. In any case,
after much persistence, it continued with the install process.
  Later, I ran across this article:

3.8 Why doesn't my Adaptec 154x work?

It appears that some 1540's and 1542's are a bit hosed by the Buslogic
probe. You will usually get an error referring to ``DMA'' in the
Adaptec probe when this happens. To fix it, you need to enter command
line parameters as follows: 

       boot:  linux aha154x=0x340 buslogic=0x334

This is assuming, of course, that the base address of your Adaptec is
0x340. If not, put your address in there instead. This will force the
buslogic to only probe an address where your Adaptec is not.

You might try that.
