Megatouch XL CD-ROM to Hard Drive

--- Quote from: obcd on September 09, 2016, 09:49:44 am ---It's impossible to know from the files if it boots or not. If you just formatted the cf card in windows, it won't boot.

In early dos days, you booted from floppy and ran the fdisk command to create partitions on your disk (cf card in this case) You had to make 1 partition active that became the boot partition.

Next, you had to format the partition.

Third, you needed to run sys c: which transferred the 2 hidden sys files and the commmand.com to the harddisk. If I remember well, the 2 hidden sys files needed to be on a specific location of the harddisk. (You couldn't just copy them over)

After this, the harddisk became bootable.

I see no other option anymore besides providing my bootable image. It's a bit of a chicken egg story. Without a bootable medium, you can't make the compact flash partition bootable..

OK could you please, please provide me with your bootable image when you get a chance?

obcd:
Ok. let's try again.

Convert a megatouch XL from cdrom to harddisk or compact flash.

Needed:
A harddisk with pata (ide) interface (Something between 1 and 10 Gig should do) or
A compact flash card of at least 1 Gigabyte and a compact flash 2 ide adapter.
A method to transfer an image to that cf card or harddisk. (A usb cf cardreader or usb 2 ide (pata) harddisk enclosure)
A program to transfer a raw image to a disk.
The files from your original cd disk. You can simply copy all contents of the cdrom to a folder.

The work:

Get my freedos bootable image.

http://www.mediafire.com/download/9w93x1vbjzaq959/megaxl_1g.zip

It's based upon freedos, so it doesn't contain any copyrighted material. (That's why I post the link here)
unzip that image to a folder. It should become an image file of nearly 1Gig (A bit smaller)

Transfer the image to your destination harddisk or cf card. Be carefull not to choose your windows drive as it will wipe out all it's contents. (I often use winhex for that. The raspberry pi website has some tools for that as well.)

remove and re insert the cf card or drive. It should come up as a drive letter.

copy all the cdrom files and folders to the mega folder of that drive letter.

Install the disk or cf card with adapter in your megatouch. Do a quick pray to your God and hope it boots...

My megatouch bios settings has all harddisks set to auto and no floppy's installed.

The drive detection is set to LBA capacity 1025
CYL 993 HEADS 32 and SECTORS 63

My mobo is a Telco.

Good luck.

I forgot 3 small details.

1. In the autoexec.bat you will find a "keyb be...." line that will set the keyboard to the belgium layout. You might change that to the keyboard layout you are using.

2. A warm reboot using <CTRL> <ALT> <DEL> isn't working. You need to power cycle the megatouch pc for a proper reboot. This is likely a motherboard bios issue and has nothing to do with the compact flash image.

3. The romdisk on the io board needs to be disabled. This can be done with the removal of jumper JP1 marked eprom enable.
JP2 is marked NVRAM Enable and shouldn't be touched. (It keeps the high scores and setup between reboots.)
JP3 is marked MFG and shouldn't be touched either.

orizzle:
Part of the problem I've noticed with my CD vs. yours is that the binaries have different names....so my script would be trying to execute something that doesn't exist.  I'm not sure of obcd's image takes this into account.

The reason my image was 4 partitions was because I was using MS-DOS and it doesn't have the subst command that obcd is using.
