Maximum size for disk image?

Hi all,

I was wondering if there’s a maximum size for an image if it will be
put on a floppy or into .altboot.

Also, can I just copy an image made by mkifs to .altboot? Or do I
have to do something else first?

All this is on RTP patch B

Cheers,
Kevin

No, you can just copy the image to /.boot or /.altboot.
Take care that your system can boot if something goes wrong.
Usually copy /.boot to /.altboot and install your image on /.boot.
Now something goes wrong but with ESC.
Maybe type “sync” before you shutdown your system.
Just make sure your image is written to disk.

The size of the image could depend on the bios, bootloader and so.
I am not really know.

Under QNX4 and on QNX6 v6.0 the size is limited by how much 640K ram
you have free. Most systems will let you get away with 570K and
some even higher. In the up coming 6.1 release there will be support
for multi-megabyte images with the new bootloaders.
