iso images are currently not supported in the swapping.
There is a patch for that and we are reworking it a bit for inclusion in the cvs.

I load my ISOs in Daemon Tools and mount the virtual drive. When I need to swap them I Alt-Enter, change the image, then Ctrl-F4. Other times I play around with combining the images from multible disks.

on linux it is currently impossible (!) to swap CDs. if you use real CDs you cannot unmount them while dosbox is running, and with images swapping is still unsupported 🙁
i really hope this patch will be included in cvs very soon...

won't be added

i finally managed to swap discs by mounting both cds in different directories (in the linux filesystem), setting a symlink to one of them, mounting this symlink in dosbox and when the game needs the other disk i make the symlink point to the other cd's directory and press ctrl+f4.
well, it works this way, but i guess i don't have to mention that this sucks. swapping images in dosbox sounds a lot better to me, it's a pity that this feature was canceled...

could you explain the reasons why we won't see image swapping in future dosbox releases?
what about some "free file-handles"-hotkey to allow unmounting of cds in linux when needed?

Because it's already there?

ok the official dosbox 0.70 readme says:

imagefile Location of the image files to mount in DOSBox. The location can be on a mounted drive inside DOSBox, or o […]
Show full quote

imagefile
Location of the image files to mount in DOSBox. The location can
be on a mounted drive inside DOSBox, or on your real disk. It is
possible to mount CD-ROM images (ISOs or CUE/BIN) as well, if you
need CD swapping capabilities specify all images in succession.
The CDs can be swapped with CTRL-F4 at any time.

but how should this look like? sry if i have missed something but iam not very skilled in such things. i think a bit more clarification or an example whould be helpfull for many users even if this feature is not well implemented yet...

Well you already highlighted what you should do,
instead of 1 imagefile specify n.

What's not well implemented there??

oops 🙄

well, i guess my dosbox build is broken then. if i try

1imgmount d cd1.iso cd2.iso -t iso

dosbox will exit with a segfault. with a single iso file it's working fine, this is why i assumed it has not been added yet...

my binary was built from a cvs checkout of the day 0.70 was released. i'll recompile from 0.70 tar.gz and see if it works then.

edit: it _does_ work with the new binary, sorry about all the trouble

i ask this because i have no idee how i should mount 2 different ISO images in one command line...
how should this look like? i tryed things like:

1imgmount d c:\cd1.iso, cd2.iso -t iso 

or

1imgmount d c:\cd1.iso / cd2.iso -t iso 

for example.
i think i get something wrong...

because of Qbixs posting:

Mabye .cue's work fine with the swapping feature?

ive tested it now with my cue/bin images of mechwarrior2 and ghost bears legacy (all 4 files are on the root of my real C: drive for testing).
using it without any characters:

1 imgmount d c:\mech2.cue gbl.cue -t iso

gives me only a "the image must be on a host or local drive" error...

Try

1 imgmount d c:\mech2.cue c:\gbl.cue -t iso

yep it works. thanks for the tip. 😀

because of Qbixs posting:

Please read the date WHEN he posted that before bashing on
the implementation quality.

2007-1-18

Has something changed since then?

A lot?

nada nothing!
DOSBox is dead. Nothing ever changes to it.

Usually the months before a release are the bussiest 😀

So before they weren't and now they are. Though with my method above I was able to swap iso images anyway.
