simh中安装运行unix v7
参考http://gunkies.org/wiki/Installing_v7_on_SIMH
一、用perl或C生成磁带镜像
$ cat mkdisttap.pl
#!/usr/bin/perl -w
use strict;
# Based on mkdisttap.pl
# ftp://ftp.mrynet.com/pub/os/PUPS/PDP-11/Boot_Images/2.11_on_Simh/211bsd/mkdisttap.pl
#
# $Id: mkdisttap.pl,v 1.1 2006/09/16 23:33:46 kirk Exp kirk $
#
# Based on the example in the HOWTO using dd. Does not work!
# add_file("cat mtboot mtboot boot |", 512);
# Based on the maketape.c program and the maketape.data data file.
add_file("f0", 512);
end_file();
add_file("f1", 512);
end_file();
add_file("f2", 512);
end_file();
add_file("f3", 512);
end_file();
add_file("f4", 512);
end_file();
add_file("f5", 10240);
end_file();
add_file("f6", 10240);
end_file();
end_file();
sub end_file {
print "\x00\x00\x00\x00";
}
sub add_file {
my($filename, $blocksize) = @_;
my($block, $bytes_read, $length);
open(FILE, $filename) || die("Can't open $filename: $!");
while($bytes_read = read(FILE, $block, $blocksize)) {
if($bytes_read < $blocksize) {
$block .= "\x00" x ($blocksize - $bytes_read);
$bytes_read = $blocksize;
}
$length = pack("V", $bytes_read);
print $length, $block, $length;
}
close(FILE);
}
c语言：
/*
* mktape.c
*/
#include <stdio.h>
#include <stdlib.h>
struct {
char *name;
int blocksize;
} files[] = {
{ "f0", 512 },
{ "f1", 512 },
{ "f2", 512 },
{ "f3", 512 },
{ "f4", 512 },
{ "f5", 10240 },
{ "f6", 10240 }
};
void error(char *msg) {
printf("**** Error: %s ****\n", msg);
exit(0);
}
void writeCount(long count, FILE *file) {
if (fwrite(&count, 4, 1, file) != 1) {
error("cannot write byte count");
}
}
int main(void) {
FILE *outfile;
FILE *infile;
long size;
int blocksize;
int blocks;
int i, j;
unsigned char buffer[20000];
outfile = fopen("unix_v7.tm", "wb");
if (outfile == NULL) {
error("cannot open output file");
}
for (i = 0; i < sizeof(files)/sizeof(files[0]); i++) {
printf("%s: ", files[i].name);
infile = fopen(files[i].name, "rb");
if (infile == NULL) {
error("cannot open input file");
}
fseek(infile, 0, SEEK_END);
size = ftell(infile);
fseek(infile, 0, SEEK_SET);
blocksize = files[i].blocksize;
blocks = size / blocksize;
printf("%ld bytes = %d records (blocksize %d bytes)\n",
size, blocks, blocksize);
if (size % blocksize != 0) {
error("file size is not a multiple of block size");
}
for (j = 0; j < blocks; j++) {
if (fread(buffer, blocksize, 1, infile) != 1) {
error("cannot read input file");
}
writeCount(blocksize, outfile);
if (fwrite(buffer, blocksize, 1, outfile) != 1) {
error("cannot write output file");
}
writeCount(blocksize, outfile);
}
fclose(infile);
writeCount(0, outfile);
}
writeCount(0xFFFFFFFF, outfile);
fclose(outfile);
return 0;
}
二、到ftp://minnie.tuhs.org/UnixArchive/PDP-11/Distributions/research/Keith_Bostic_v7/下载
f0.gz f1.gz f2.gz f3.gz f4.gz f5.gz f6.gz并解压为:f0 f1 f2 f3 f4 f5 f6
三、生成磁带镜像文件：
$ ./mkdisttap.pl > v7.tap
或
$gcc -Wall -g -o mktape mktape.c
$./mktape
或
直接到http://sourceforge.net/projects/bsd42/files/Install tapes/Research Unix/Unix-v7-Keith-Bostic.tap.bz2/download下载Unix-v7-Keith-Bostic.tap.bz2解压后修改名字
$ mv Unix-v7-Keith-Bostic.tap v7.tap
四、安装
$ vi tapei.ini
$ cat tapei.ini
set cpu 11/45
set cpu idle
set rp0 rp06
att rp0 rp06-0.disk
att tm0 v7.tap
boot tm0
