Re: [N8VEM: 14994] Re: CF and SD card images
Here are John's images for sharing with the full MD5 hash in the file name... they are 4gb at this time and if using in S100 IDE reader, John's IDE board supports this 4GB Kingston CF card with the flowers on it:
their are files on User 0-->6, its CP/M 3.0 banked
Both boot fine if ZFDC is installed, but if your remove it, JM2
boot correct, JM1 has a booting issue, well continue to re-boot... works best if both CF are installed. CP/M 3.0 Banked. files on User 0
are different on the cards, other user look the same. Boot with A:
IDE-1, B&C 8in Floppy, D 5 1/2 floppy, E MDisk (1mb), F 2nd IDE, G
ST506 Dsik drive
Support for MSDOS board RTC
If you have luck with other cards, let all of us know...
The two images from John Monahan have been posted on the server at these URL's...

I'm using this approach as well.
To add to the story:
- the disk images created this way can be read from & written to by the Simh N8VEM emulator, which has become my main file import/export mechanism.
- The cpmtools can also work on the images (although I still have a problem with the settings actually).
- Also, the same image file/CF card can be used interchangeably on my Zeta/Prop board, the Disk I/O board and the PPIDE.
It's a very nice side-effect from the unified RomWBW approach.
I did have problems with some CF cards that Win32diskimager did not want to write images to. In those cases, a simple format under Windows fixed the problem.
Lastly, the Win32diskimager always makes an image of the entire CF card. It would be nice if it only imaged to first 256MB or so - then you could exchange images to CF cards of various sizes. And actually, partitions beyond the 256MB would then be left untouched.

There is a well supported, free CF/SD card Image program for the PC..
It maybe of great use to us who have CP/M system with CF and SD cards to make copies, share and save images.
I have tested it under Win XP, Win 7, 32 and 64 bit. and Mac OS running VM Fusion
It is use by the Raspberry Pi (An ARM GNU/Linux box for $25) for sharing boot images..
Is compatible with other "DD" image programs on the MAC and Linux system.
I have use it to copy John Monahan, CF card for his S100 IDE board and Zeta CF and SD cards,
To use I start the program...
Insert a CF or SD card into your card reader... (after the program is started)
If Windows want to take some action on the card, say cancel to it message.
To Read a card, Select an image file name: ie: mycard, set the path with the small box with a folder on it...
In the device box, select the device letter for the CF/SD card... Be sure you know what drive your writing too!... Check the drive letter twice!!
Click READ to read the card...
When finish, select the MD5 button to generate an MD5 Hash of the card...
I keep only the last 6 digits of the hash and write this on the master CF/SD card image when I make one.
I also add it to the file name: mycard_md5hash so that I remember it. The MD5 is generated from the FILE image,
NOT from the card!
I Always read a new card twice, to a 2nd file name, ie: mycard1, to check that the MD5 hash is the same!
To Write a card, select the file-image to write into the Image File Box, select the device letter
When its finish, I always read it back to a NEW file name, ie: mycard2 to check that the MD5 hash is correct.
good luck, lets see some images saved on the web site for all of us to use!!
also, let us know what make an model of CF - SD card you have tested with!
