Megatouch XL CD-ROM to Hard Drive

<< < (13/26) > >>

obcd:
I downloaded the image and transferred it to my 4Gig cf card.
In windows, it only showed the first partition.
So, started my virtual debian and made my cardreader usb available to it. I got the 4 partitions.
Wiped the /dev/sdb7 clean and transferred your files to that partition.
Installed the CF card in my megatouch XL. It booted dos, but could only see the c partition.
So, I ran fdisk and noticed that it showed no logical partitions in the extended partition.
So, I deleted the extended partition and created a new one of approx 1 gigabyte.
I created 4 logical partitions into that extended partition. 3 of 50 MB and the fourth using the rest of the available space.
After a reboot, I formatted the D, E  and F drive.
Connected it back to linux. Struggled a bit to mount it writable

sudo mount -tvfat -o user,umask=0000 /dev/sdb7 /home/xxx/mount

finally did the trick.

copied your files over to that partition.

Installed the cf card back in my megatouch.

It booted into dos and....

Hard Drive Shock Mount Failure !!!

This is starting to irritate me....

Next test will be with the files again that originally where on the F partition. (Out of curiousity...)

DaddyLongLegs:
Maybe the Megatouch somehow can detect that nothing is resting on the CD-ROM caddy? I have no clue. I don't even know why the program knows to ask about a hard drive considering it was a CD game.

Maybe Orizzle can chime in on how he got the error to not show up when he made his XL 5000 run from a CF?

obcd:
I just tried with Orizzle his files and they give a
ERROR   Invalid Key !!!
Which is pretty much expected behavour.

I noticed that there are some zero length files in his folder with some strange names like AAADDIDC.
There is no such thing with your files.

They could figure out that the files are transferred from cd to harddisk as they are no longer having the "read only" attribute set.

So, I basically have 3 cd versions that run normally from a compact flash card and yours that gives a
Harddrive shock mount failure.

I'll do one final test with your files all set to read only. It's just a wild guess, but who knows.

The second post talks about using a harddrive and says that it's not possible with the gold edition...
So, they put something in to prevent a harddrive copy from working.
If it's not documented somewhere, only reverse engineering the code could give a clue how the conversion to a compact flash card is detected.

OK so I am willing to use the CD-ROM drive. Never in a million years did I think this thing could detect a hard drive and prevent it from booting but here we are. Anyway, is there a way we can make my CD-ROM bootable? That way I will simply keep using the CD-ROM. Maybe put FREEDOS somewhere on the CD?
