I do not care about kernel debugging. I do not care why my system crashes. (it never does, unless I L1-a it) what I DO care about is more swap space. Currently, my 4/110 running 4.1.1 has about 100 megs allocated for swap space. but half of it goes to "dump" space. How do I get rid of that useless "dump space" reservation??? I've recompiled the kernel without the kernel debugging option (I think) but it stil reserves dump space. I know this, cause on boot, for the main sd0b, it says: 14 megs reserved for swap 14 megs for dump or something like that. I believe my other swap device is also being wasted. Even when I make a swapfile, it seems to only add half the size of the file as additional swap. ------------------------------ Date: Mon, 26 Apr 93 23:41 CDT From: eberg@chinet.com (Erik Arthur Berg) Subject: need help with cd-rom on 3/60c To: suns-at-home-request@ecn.purdue.edu I have Unix Power Tools by O'Reilly and Bantam publishers which is a book of unix tips and includes a cd-rom containing pd software (perl, ispell, bash, etc.) binaries and source for Sun3's & 4's. I have a NEC-73 cd-rom drive with centronics connectors which I would like to connect to my shoebox but can't find a cable. My questions: 1. Will this drive even work with the 3/60? If not what cd drives will work other than Sun drives? 2. Where can I find a cable with male centronics and db50 ends? Should the cable be straight through or do I have to cross some signals? 3. Are there any configuration tricks to get cd-roms to work on 3/60's? I only have an installation manual. The 3/60c has 16 megs of ram, a CG4, SunOS 4.1.1 and a shoebox with a 1/4" tape drive and 1 ESDI disk with a scsi interface(?). I am pretty new to Sun so be gentle with me...Thanks for your help. ---- Erik Berg eberg@chinet.chinet.com ------------------------------ Date: Mon, 26 Apr 93 09:45:39 CDT From: aqn@tivoli.com (Andy Nguyen) Subject: Problem adding a new SCSI disk to a Sun3/60 To: Suns-at-Home@ecn.purdue.edu I wrote: + I have a Sun 3/60 SunOS 4.1.1.

The answer: the second digit really is the SCSI ID of the particular device. I jumpered the new drive's SCSI ID to be 1. Then made this change in /usr/kvm/sys/sun3/conf/GENERIC_SMALL: disk sd1 at si0 drive 001 flags 0 disk sd2 at si0 drive 010 flags 0 to: disk sd1 at si0 drive 010 flags 0 disk sd2 at si0 drive 020 flags 0 Rebuilt the kernel, and now everything works fine. "format" does indeed discover the new drive. (btw, when I was failing to boot, it looked like it was because of some sort of SCSI errors, not because the new kernel was not bootable. I was getting the error message: getbyte error, phase mismatch invalid status message: FFFFFFFF when I do the 'b' to boot at the Monitor Prog prompt. Turned out, it was something weird with the SCSI stuff: if I powered everything down before powering up again, it's OK. (I was just leaving everything ON and pulling the power plug of the new drive.)

Wargo) Subject: Problem adding a new SCSI disk to a Sun 3/60 To: suns-at-home@orchestra.ecn.purdue.edu This is not an uncommon problem/misconception. Before the Sun-4 series, Sun (more or less) took advantage of SCSI LUN's as well as targets. What's a LUN, you ask? Well, LUN stands for Logical Unit Number, and there are 7 LUN's available for each target. (target=SCSI ID #) Now, Early Suns took advantage of LUN's, but only two per target. This is because adaptors like the ACB-4000 (SCSI<->MFM) and the MD-21 (SCSI<->ESDI) offered the ability to connect two drives to each board, each having its own LUN, while the board took up one SCSI target. So, using the 3/60 as an example, here's what the drives looked like: /dev/sd0 = Target 0, LUN 0 /dev/sd1 = Target 0, LUN 1 /dev/sd2 = Target 1, LUN 0 /dev/sd3 = Target 1, LUN 1 /dev/sd4 = Target 2, LUN 0 /dev/sd5 = Target 2, LUN 1 /dev/sd6 = Target 3, LUN 0 /dev/sd7 = Target 3, LUN 1 At this point, targets 4&5 are generally reserved for /dev/st0 and /dev/st1, respectivly. Target 6 is commonly used for a CD-ROM. (/dev/sr0) (I believe this was only in 4.1.1. Correct me if I'm wrong, but I don't remember CD support in 4.0...) So, in the case of the 3/60 that won't boot, remember that the boot drive is an ESDI disk attached to an MD-21 controller. This accounts for /dev/sd0 & /dev/sd1. Changeing the kernel config file back and setting the new drive to tarrget (ID) 1 will result in the new drive being seen as /dev/sd2. (It's a shame that embedded SCSI drives can't be assigned to different LUNs.) Remember to terminate the chain! (Remove the resistor packs from the MD-21 and install the ones included w/the SCSI drive. (Assuming, of course, that the SCSI drive is the last in the chain...) Good luck, and I hope this helps. -Pete Wargo ------------------------------ Date: Tue, 27 Apr 93 09:14:26 EDT From: bwalker@auratek.com (Brad Walker) Subject: Telebit QBlazer modem for sale To: suns-at-home@orchestra.ecn.purdue.edu I have a couple of Telebit QBlazer modems that I need to part with.
