(TK50, TU81, ...) 11 ts - TSV05/TS11 tape. 12 ra - RA??/RD?? disks/floppies. 13 hp - RP??/RM?? disks. 14 rd - RD?? disks on MicroVAX 2000. 15 sd - SCSI disks. 16 st - SCSI tapes. 17 le - LANCE ethernet controller. 18 19You can omit parameters; ra(0,0) refers to disk 0 partition a 20on default controller. On tapes partition refers to file # 21on the tape. 22 23Example: DUB1 (DEC syntax) swap partition will be referred as 24 ra(1,0,1), DRA2 root partition is hp(2,0). 25 26 27The installation principle is to label the root disk, copy a miniroot 28filesystem onto the swap partition, boot up from that miniroot filesystem, 29then create root and the other wanted partitions and put system to it. 30You will have to deal with 2 different "units", one is just a boot 31filesystem containing 3 files: boot, copy and edlabel, the other is an 32image of a miniroot filesystem and can be split into several pieces 33depending of what you are going to install from. 34 35 36Installation from tape: (MicroVAX II/III) 37Take your newly created boot tape and just boot from it: 38 39 >>> B/3 MUA0 40 41This means that you will bring upp boot to aks for boot file from TK50. 42(MUA0 is DEC naming). It will come up something like 43 44 2..1..0.. 45 46 47 howto 0x3, bdev 0x12, booting...done. (31248+22252) 48 49 >> NetBSD/vax boot [970610 23:44] << 50 : 51 52 53At the prompt you type edlabel to label the disk, see below about 54how to use edlabel. 55When labeling is finished, halt the computer, bring up the boot program 56again and this time load copy, see below about how to use copy. 57Remember that you must copy from the second file (1) on the tape. 58 59Now go to step 3. 60 61 62Installation from RX33/RX50. (MicroVAX II/III) 63The difference between RX33 and RX50 is its size. RX50 is 400k and 64RX33 is 1200k. 65 66To boot from floppy type: 67 68 >>> B/3 DUxy 69 70where x is the controller number and y is device number. 71You will now get up a prompt like 72 73 >> NetBSD/vax boot [970610 23:44] << 74 : 75 76At the prompt you type edlabel to label the disk, see below about 77how to use it. 78When labeling is finished, halt the computer, bring up the boot program 79again and this time load copy, see below about how to use it. 80Remember that you are will copy from partition 0 when using floppies. 81 82Now go to step 3. 83 84 85Installing over network: 86 87 88You can use the same flags when booting over the net as when 89booting from local disks; like: ">>>B/3 ESA0" will load boot 90in ask state. From here you can load any file you want, even 91copy and edlabel if they are located in the exported root fs. 92 93Note 1: Netbooting of MicroVAX II/III systems with DEQNA/DELUA 94 ethernet does not work does not work yet because lack of standalone 95 drivers. Mounting of root and swap over NFS works goos though. 96Note 2: Mopd won't work on VAXen with de/qe ethernet, due to the 97 lack of bpf support for those interfaces. 98 99Booting up miniroot. 100When copying is ready, bring the boot program up a third 101time, and this time bring up a real system by telling 102boot where you put your miniroot _and_ also the generic 103kernel name. Example: ra(0,1)gennetbsd, boots gennetbsd 104from swap partition on ra0. 105 106When kernel is loaded, you will after a while get a 107question about Root device?. Respond to this with 108xx?*, where xx is the device name, ? is the unit 109number and * tells that the system shall use the swap 110partition as root partition. Example: 111 112 Root device? ra0* 113 114After that a second question: 115 116 Enter pathname of shell or RETURN for sh: 117 118Just type return. Now you will be in a normal single-user 119shell, and it's just to newfs your partitions, and start installation. 120 121A few things that you must remember to do from miniroot: 122disklabel -B <diskname> to install boot blocks. 123MAKEDEV devices in the newly created root filesystem. 124Copy gennetbsd and boot from miniroot filesystem 125to the newly created root filesystem. 126 127How to use edlabel: 128Edlabel is a program to edit disklabels on any disks in a standalone 129environment. Mostly it is used to set labels when doing initial 130installation procedure. It is started from boot program prompt. 131You will here be guided through a session, things with ^^^^ under 132is typed in by the user, comments are within /* */. 133 134 >> NetBSD/vax boot [970610 23:44] << 135 : edlabel 136 ^^^^^^^ 137With this program you can modify everything in the on-disk 138disklabel. To do something useful you must know the exact 139geometry of your disk, and have ideas about how you want 140your partitions to be placed on disk. Some hints: 141The a partition should be at least ~20000 blocks, the 142b (swap) is depending on your use of the machine but it 143should almost never be less than ~32000 blocks. 144 145Disk geometry for most DEC disks can be found in the disktab 146file, and applicable disk names can be found above. 147 148Remember that disk names is given as disk(adapt, ctrl, disk, part) 149when using the installation tools. 150 151Label which disk? ra(1,0,0) /* See INSTALL text for device types */ 152 ^^^^^^^^^ 153getdisklabel: no disk label 154ra(1,0,0): no disk label 155(E)dit, (S)how, (D)efaults, (W)rite, (Q)uit) : e 156 ^ 157First set disk type.

Mostly it is used to copy the 252miniroot filesystem onto the swap partition during initial 253installation. 254You will here be guided through a session, things with ^^^^ under 255is typed in by the user, comments are within /* */. 256This is an installation from TK50. 257 258 259 >> NetBSD/vax boot [970610 23:44] << 260 : copy 261 ^^^^ 262 263copy: 264This program will read miniroot from tape/floppy/disk 265and install this miniroot onto disk. 266 267Specify the device to read from as xx(N,0), where 268xx is the device-name and N is the unit-number, e.g. 269"mt(0,1)" for the first TMSCP-tape (TK50), 270"ra(2,0)" for the third MSCP-disk/floppy (RX33/RX50) 271 272device to read from ? mt(0,1) /* Tape 0, file 1 */ 273 ^^^^^^^^ 274Specify number of blocks to transfer. Usually this is 275sizeof(miniroot) / 512. 276It's safe to transfer more blocks than just the miniroot. 277 278number of blocks ? 4096 /* Miniroot size is 4096 block */ 279 ^^^^ 280If your miniroot is split into volumes, then you must 281specify the number of blocks per volume. 282(e.g. 800 blocks per RX50, 2400 blocks per RX33) 283 284number of blocks per volume ? [4096] 285 286Make sure unit tms(0,1) is online and holds the proper volume. 287Then type 'g' to Go or 'a' to Abort. 288 289OK to go on ? [g/a] g /* g == go, a == abort */ 290 ^ 291Reading ... Reading of miniroot done. (4096 blocks read) 292 293 294Now specify the device to write miniroot to as xx(N,1) 295where xx is the drive type and N is the drive number. 296For example: ra(0,1) refers to MSCP drive #0, b partition 297 298Root disk ? : ra(0,1) /* Actually DUA0, partition b (swap) */ 299 ^^^^^^^^^ 300Initializing partition ... done. 301(4096 blocks written.) 302 303Halt the machine and reboot from distribution media, 304giving second partition as part to mount as root. Ex: 305: ra(0,1) for ra disk 0, hp(2,1) for massbuss disk 2 306 307Halt/Reboot the machine NOW. 308?02 EXT HLT 309 PC = 001005F3 310>>> 311 312 313
