I know - most of you are in disbelief that such people do exist. We do! Now this is not to say that I can't program - I can. I just don't like learning a specific language's syntax to the point where I avoid programming (that or I delegate it...) So the sources fall lower on my list of references than they should. If Linux is going to succeed with the General Public it's going to need to deal with a greater percentage of people like me. Either that or we should talk about a rewrite in COBOL. :) > but i think it's nice for other people to know where you can find such > informations. > Absolutely!!

It's there. Though there are 220 or so files in /usr/src/linux/drivers/scsi alone...finding a reference to an option you don't know in the source of a driver you don't use *is* somewhat problematic. It's akin to using a dictionary to learn the proper spelling of a word - it's easy to find the word if you already know how to spell it... Thanks again, I'll see if I can get over there tonight to do a re-boot.

But for the lilo option it's no_reset ex: aic7xxx=no_reset (change aic7xxx to the name of your SCSI driver) you can put it in lilo.conf like that append="aic7xxx=no_reset" or otherwise on the lilo prompt you can type: linux aic7xxx=no_reset if linux is the name of your kernel Good luck Patrick Ps: to find things like that see the kernel sources. for example aic7xxx=no_reset (along with all other options) is clearly mentioned at the beginning of /usr/src/linux/drivers/scsi/aic7xxx.c
SMP & SCSI resets
Howdy All! I've finally got my SMP machine spinning both CPU's. (Seems that the MB was jumpered wrong...) However, when I boot the system the Adaptec SCSI Controller gets stuck while resetting. I seem to remember reading somewhere a LILO/boot command-line option to turn-off SCSI reset. Unfortunately, I've not been able to locate the reference. Could one of you kind folks either point me in the right direction, or even (***gasp***) tell me the answer! :) It'll be fun having both CPU's *and* SCSI drives (seeing how this is a SCSI-only system it's kinnda important for those drives to be available...)
