Good to hear that, but how did you manage it? Can you please give a hint?
I tried it yesterday night (for >6 hours...) with all kind of cards (1GB SanDisk ExtremeIII, 2GB SanDisk normal, 1 GB no-name) - without any results.
Using the syslinux method (
http://ben.franske.com/blogs/bensbits.php/2007/08/21/booting_dos_from_a_usb_flash_drive) I got a boot prompt and a "Loading FreeDOS" - but that's it.
To anyone who already booted FreeDOS: can I expect any FreeDOS output at the serial console? Or will there just be nothing? Would I have to update the BIOS using autoexec.bat/fdauto.bat?
Has anyone had any success (or know if it's possible) to create a netboot image for freedos? I tried dozens of times in a variety of different configurations to make it work all to no avail. However, I think if there was a way to pull it off it might lend itself better to people who don't have a compatible CF card.
After throwing my CF cards at the wall

I also tried the PXELINUX way. I already have DHCP and TFTP running here, so this wasn't too much action. But I don't get very far this way - my ALIX gets an IP address via DHCP, loads the
pxelinux.0, then the pxelinux.cfg/default, and that's it. Some PXELINUX prompt appears, but nothing more - no more TFTP requests (not even for the
memdisk image). Here's my default config file for PXELINUX:
SERIAL 0 38400 0
timeout 50
default fdos
prompt 1
say PXE_2
label fdos
kernel memdisk
append initrd=fdboot.img
Leaving the SERIAL option away doesn't help; the 'say' command was used just for debugging, but I don't even see that at the console.

A minimalistic config file (containing only the last three lines) showed no different behaviour.

My board is an ALIX2.3 with Bios 0.98b. This afternoon I'll have a look at a computer store around the corner if they have some 128 meg CFs.
UPDATE: no-one here still has that small CF cards... I'll have to buy one at eBay. Must be patient...
