Lines: 91 Hi, I've got some problems installing 386BSD "by hand". Until last weekend I had a fine working system (Thanks to all who made this possible!) of DOS and BSD until I decided to do some "real partitioning"... So here's my problem: I have a 486/33 ISA Board with 8MB RAM, a 500MB Conner CP3504 IDE HD, a 100MB Conner CP3104. I had BSD working in a 450MB partition (along with 50MB DOS) on the first HD. Now I want to divide the BSD partition as follows: a: 40MB / b: 20MB swap d: 70MB /usr e: remaining /volumes Following the instructions posted here recently, I started building a disktab entry using the boundaries for the 'c' partition from my previous installation. (I've included this info at the end.) Whenever I tried to boot DOS after "newfs /dev/rwd0d", I get a "no operating system" message. (BTW, I have os-bs132 installed.) This is what disklabel -r wd0 said before I started building my own: > type: ESDI > disk: ESDI/IDE > label: 12MB - CP350 > flags: > bytes/sector: 512 > sectors/track: 63 > tracks/cylinder: 16 > sectors/cylinder: 1008 > cylinders: 987 > rpm: 3600 > interleave: 1 > trackskew: 0 > cylinderskew: 0 > headswitch: 0 # milliseconds > track-to-track seek: 0 # milliseconds > drivedata: 0 > > 3 partitions > # size offset fstype [fsize bsize cpg] > a: 879984 102816 4.2BSD 1024 8192 16 # (Cyl. 102 - 974) > b: 10000 983388 unused 0 0 # (Cyl. 975*- 985*) > c: 891072 102816 unused 0 0 # (Cyl. 102 - 985) So I made my disktab entry: > cp3504|Conner Peripherials 500MB IDE: \ > :dt=ST506:ty=winchester:se#512:nt#16:ns#63:nc#987: \ > :pa#82656:oa#102816:ta=4.2BSD:ba#8192:fa#1024: \ > :pb#41328:ob#185472:tb=swap: \ > :pc#891072:oc#102816: \ > :pd#151200:od#226800:td=4.2BSD:bd#8192:fd#1024: \ > :pe#611856:oe#378000:te=4.2BSD:be#8192:fe#1024: and labelled the disk. ok. But what am I doing wrong???? I've checked several times that no partition overlaps any other or even my DOS partition (Cyl. 0 - 101). I've even tried to make some partitions smaller to leave some space for the bad sector table; although I must admit I haven't understood this completely (I always thought IDE drives handle this internally). Do I have to add an ':sf:' in the disktab entry??? BTW, what does the '*' mean in the table above??? I would highly appreciate if any kind soul could point me in the right direction.
