[Coco] SuperIDE and CF Cards

[Luis Antoniosi (CoCoDemus)]

dd just works on cygwin. But there is a catch: I always use megabyte block
copy:


Using a 256mb C-9 stock CF to extract its image:

dd if=/dev/sdb1 of=cfimage.img bs=1M count=245

to put an image on it:

dd if=cfimage.img of=/dev/sdb1 bs=1M count=245


Of course you should look at proc/partitions to see which one is your local
cf card. In my case is /dev/sdb1:

cat /proc/partitions


You can also use toolshed to handle files on the very first os-9 partition
just like this:

os9 dir /dev/sdb1,
os9 dir makdir /dev/sdb1,EXTRAS
os9 copy file /dev/sdb1,EXTRAS/file

and so on.

but to get/put a hdbdos image on it you should use my command line tool:

side put image.dsk 240 /dev/sdb1

side get image.dsk 240 /dev/sdb1

of course, supposing you are using default 0x052ddc offset.

Compile the following program on cygwin: gcc side.cpp -o side and put it on
/usr/local/bin:


#include <stdio.h>
#include <stdlib.h>
#include <string.h>

char g_imageFilename[1024];
char g_cfDevice[1024];

#define OPMODE_GET 0
#define OPMODE_PUT 1

int g_opMode = -1;
int g_imageNumber = -1;
int g_hdbdosOffset = 0x52ddc;

int g_numOfDrives = 256;
int g_numOfSectors = 500700;

void printError(const char *msg)
{
printf(msg);

printf("Side 1.0\nHDB-DOS virtual disk tool for Cloud9 SuperIDE CF

printf("\nUsage:\n\n");
printf("\nside [get|put] <hdb-dos image> <drive number> <cf device|image

printf("where options are:\n\n");
printf("-s <total number of sectors> : Default 500700\n");
printf("-d <total number of drives>  : Default 256\n");
printf("\nExamples:\n\n");
printf("side get disk10.dsk 10 /dev/sdb1\n");
printf("side put games03.dsk 35 /dev/sdb1\n");

exit(1);
