 CONFIGURATION ARGUMENTS:

 IOPORT        base io address                           (0x340/0x140)
 IRQ           interrupt level                           (9-12; default 11)
 SCSI_ID       scsi id of controller                     (0-7; default 7)
 RECONNECT     allow targets to disconnect from the bus  (0/1; default 1 [on])
 PARITY        enable parity checking                    (0/1; default 1 [on])
 SYNCHRONOUS   enable synchronous transfers              (0/1; default 0 [off])
 (NOT WORKING YET)
 DELAY:        bus reset delay                           (default 100)
 EXT_TRANS:    enable extended translation               (0/1: default 0 [off])

 LILO COMMAND LINE OPTIONS:

 aha152x=<IOPORT>[,<IRQ>[,<SCSI-ID>[,<RECONNECT>[,<PARITY>[,<SYNCHRONOUS>[,<DELAY> [,<EXT_TRANS]]]]]]]

 SYMBOLS FOR MODULE CONFIGURATION:

 aha152x=IOPORT,IRQ,SCSI_ID,RECONNECT,PARITY,SYNCHRONOUS,DELAY,EXT_TRANS
 configuration override of first controller

Usually you'll only need to specify the first two arguments (the
port address and IRQ), like this: "aha152x=0x140,11", etc.  You
set the IRQ and port address using jumpers on the card, typically.

I would just go down to Digilink or CompUSA and pick out a cheap
card that used a supported chipset--e.g., sym53c8xx or aic7xxx or
BusLogic, to name a few.  A printout of `ls' output for the
kernel's drivers/scsi directory might be helpful for this.
