Write CF from OSX

[Beebe]

I have a new OSX machine here, and I'm having trouble using it to write a CF card for use in wrap boards. It does recognize the CF Card when I plug it in - it appears on my desktop.

I've become root user and tried to use dd to copy the image and I get this:

roger-hs-computer:/users/rogerh/staros/wrap root# dd if=vncOs-1.1.13-2080.X86-WRAP.cf of=/dev/disk1
dd: /dev/disk1: Resource busy

Can anyone see what I'm doing wrong?

Thanks,
Roger

If it helps...

It's the TOSHIBA512M that I'm trying to write to.

Simply unmount /Volumes/TOSHIBA512M before you 'dd' the CF, and things should be A-Ok.

Great, that worked. Thanks. I thought "ejecting" it from the desktop was the same as doing a umount, but apparently not.

Cheers!

I'm trying to do the same thing, except with vncOs-1.1.13-2080.X86-PC.cf

If I do an "od" (octal dump) the file and the compact flash compare, but when the PC boots, I get an "L 99 99 99 99 .... 99" for half a screen. I've tried 2 computers and get the same result.

I have also gone back and compared the original file at files.star-os.com with the one I dd'ed. The MD5 matches.

I don't have an immediate need for this, just wanted to experiment with the PC version of StarV3. (the CF-to-IDE converter I'm using worked a year ago with Mikrotik)

[Oh, would a bootable CD work for this purpose? Or does the CF need to be writeable -- never mind, I just figured that out, must be writeable, otherwise the settings couldn't be saved -- no way to save the config on yet another USB memory stick, right?]
