boot parameters

[Phil Reardon]

Hello:  I would like to go to debian from my present redhat 5.1 system.
I have an Adaptec 2920 controller and a Seagate ST-34555N disk.  Both of
these may require some parameters at the boot prompt .  My question is,
given that I am now using linux, how can I find out what those
parameters should be?  For the controller I think I need iobase(?),
irq(?), scsi-id (=0), and reconnect (?).  For the disk I need
mbm-base(?) and irq(?).   So I now only know one out of the six
parameters.  Can you help, please?
