I got IDE emulation working on openMSX, but...How can I add large files to HD.dsk?

For example, I want to add some EVA files (each around 10-20Mb) to the IDE image created by openMSX, but there's no way I can copy those to disks and then to the HD image... is there any utility to add/remove files from HD.dsk?

There is no such tool yet, but David (turbor) is busy writing one.

Only way to add files is to have the HD.dsk on drive A: whilst having drive B: pointed out to a REAL folder on PC and use copy command from B: to A:

itsa damn pitty any DSK manager proggy can only handel flop-formats (e.g. 720 kb). . . .

Slotman: you can also use a method that you would use in case of a *real* harddisk on MSX with only real floppy drives available.... (Don't know which method, but hey, it's exactly the same situation! :-)

SLOtman,
If you want I can send you an alpha of my tool
Only restrictions so far:
1) I develop it on Linux and do not have a Win32 compile environment, so I can only provide a Linux binary, and I can't even test if it wil compile under Windows(tm)
2) I only tested with FAT12 so far and do not have a FAT16 available for testing

rgds,

Turbor

turbor: Hmmm... I dont have linux here, but maybe I could port it to DOS? well, send me the binary, I'll see what I can do with it. The FAT12 issue wouldnt be a problem, if a file is bigger than 32Mb I can cut them into 2 16Mb files and then assembly it together on MSX... thanks for helping me out!

ro: to transfer 20/30Mb files over disk drives are INSANE! Each disk is 720 kb, so in "rough math": 30/0.7 = 42 disks!

manuel: in a real MSX I would just burn those files on a cd-rw on the PC, put it on a cd-rom on MSX and copy it to the harddisk... if openMSX could access the CDROM drive as an IDE CD... =)

Another thing, I saw on openmsx web site that there is joynet support on openmsx? Isnt there an utility to transfer files from PC to MSX using joynet? I googled for it but couldnt find anything... but maybe can this be an answer to my problem?

Thanks everyone!

SLotman, how do I contact you ?
You do not have any userinfo on the mrc available for the public...

Also what good is a Linux binary for you if you do not have Linux? Are there tools to run those binaries on DOS ? Wouldn't it be more logical to give you sources ?

To contact me: msxfiles@*nospam*uol.com.br (please remove *nospam*)

I asked the linux binary, cause I would install slackware or something to run it here... but if you're willing to share the sources, sure, send them =)

Thanks in advanced!

I've not tried the HD emulation thing yet, but I use Winimage for my DSK files... It's a winzip look-a-like which supports DSK files.

Since turbor's little project here is part of the openMSX project, the source code is freely accessible and licensed under the GPL
Check it out here: http://cvs.sourceforge.net/viewcvs.py/openmsx/msxtar/

turbor is still heavily developing it, so no guarantees of course

(btw: hi David! ;-)

Yup, and there I am, wanting to make it a little more userfriendly with some more testing before I announced it to the world... *sigh*
So much for that plan

Well,

First of all, thanks everyone...

I've successfully ported msxtar to MS-DOS widht DJGPP, but the bad news is that msxtar does not help me =(

I've created a 600mb HD image with two partitions, one with 32Mb and the other with the remaining space. The problem with msxtar is that it re-creates the dsk file in memory, so it just crashes back to DOS saying "fatal error: not enough memory", since there's no way DOS can handle 600mb files on RAM 8(

Is there any other way to put files on a disk image on openmsx?

MeitsNearDark: winimage does not recognizes correctly HD images as valid DSKs (if does recognize two partitions, but stops on that)

Update: I created a second HD image to use with openMSX as slave - 32Mb size, so now msxtar can add files to it... but anytime I try to add a file (any file, small or big) the HD image gets corrupted... what could be the problem?

The output generated by the program:

maxCluster 4087
RootDirStart 25
RootDirEnd 40
---------- Boot sector info -----

bytes per sector: 512
sectors per cluster: 16
number of FAT's: 2

Couldn't find entry teste.txt to update, trying to create new entry
Adding file teste.txt
teste.txt -> "TESTE TXT"

Instead of trying to update the diskimage, could you try creating a new one with msxtar itself ? like this:
msxtar -cvf new-hd.dsk --size=ide teste.txt

To be honest, due to my way to limited available freetime, this is so far the only thing I actually tested. I never started updating with an existing HD image so far (unless this one was also already created with msxtar(read: unpartioned) )
By using the --size parameter like this, there is no partition info on that 32 MB diskimage.
And with my 'real HD image'(read: partitioned) all I have done so far is extracting
Like stated in earlier mails, this is all in development for now...

A possible cause why this update could go wrong, is because of the fact that I for now blindly assume a certain version of IDEFDISK to be used...
Which version do you use when partitioning/formating the HD image?

Message for Turbor!
Sorry for posting a "private" item in this forum: I wish to contact Turbor but I can't find any userinfo on the mrc available for the public.
So please, David would you be so kind to contact me or let me know how can I communicate with you?

Apologize me for the interference
