Disk partition sizes and offsets 162are in sector (most likely 512 bytes) units. Make sure these size/offset 163pairs are on cylinder boundaries (the number of sector per cylinder is 164given in the `sectors/cylinder' entry, which is not shown here). 165 166Do not change any parameters except the partition layout and the label name. 167It's probably also wisest not to touch the `8 partitions:' line, even 168in case you have defined less than eight partitions. 169 170[Example] 1718 partitions: 172# size offset fstype [fsize bsize cpg] 173 a: 50176 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 111) 174 b: 64512 50176 swap # (Cyl. 112 - 255) 175 c: 640192 0 unknown # (Cyl. 0 - 1428) 176 d: 525504 114688 4.2BSD 1024 8192 16 # (Cyl. 256 - 1428) 177[End of example] 178 179__md_prep_disklabel_1 180 echo -n "Press [Enter] to continue " 181 getresp "" 182 disklabel -i -I /dev/r${_disk}c 183} 184 185md_copy_kernel() { 186 echo -n "Copying kernel..." 187 cp -p /netbsd /mnt/netbsd 188 echo "done." 189} 190 191md_welcome_banner() { 192 echo "Welcome to the NetBSD/mvme68k ${VERSION} installation program." 193 cat << \__welcome_banner_1 194 195This program is designed to help you install NetBSD on your system in a simple 196and rational way. You'll be asked several questions, and it would probably be 197useful to have your disk's hardware manual, the installation notes, and a 198calculator handy. 199 200In particular, you will need to know some reasonably detailed information 201about your disk's geometry. The kernel will attempt to display geometry 202information for SCSI disks during boot, if possible. If you did not make it 203note of it before, you may wish to reboot and jot down your disk's geometry 204before proceeding. 205 206As with anything which modifies your hard disk's contents, this program can 207cause SIGNIFICANT data loss, and you are advised to make sure your hard drive 208is backed up before beginning the installation process. 209 210Default answers are displyed in brackets after the questions. You can hit 211Control-C at any time to quit, but if you do so at a prompt, you may have to 212hit return. Also, quitting in the middle of installation may leave your 213system in an inconsistent state. 214__welcome_banner_1 215} 216 217md_not_going_to_install() { 218 cat << \__not_going_to_install_1 219 220OK, then.
