DSL Tips and Tricks :: DSC-II or Damn Small Capio II

The first problem, that of finding a programmer was solved when I realised that the Lex Embedded Light CV860A that I'd bought a while back to be my router has a DOC socket in it and the ability to boot from CD/floppy/HDD etc. Not a cheap solution if you dont already own one

Using this I managed to install freedos and used the autoexec.bat to automatically run a dos executable etherboot .com file. You can generate these at http://rom-o-matic.net/. If I remember correctly the network card is a standard eepro100 and I think the ROM required is the eepro100:82559er (although it says only the family is required for .com generation). I havent tested this though, I used a fairly universal etherboot .com file that I found here in the network_boot_floppy+cd+hd_540.zip file. That way I could get it all working in my Lex system and only move it across once I was finished.

There is probably a far neater way of doing this

I have been using this setup with limited success booting LTSP 4.1.

PS.300c_pilot: I had some issues with formatting my DOC, although it did appear initially as c:. You need some special tools from the m-systems website. DInfo(?) was able to see my DOC even after I messed it up and tell me the address to write the firmware image back to (once i'd done this it came up as c: again).

Checking it all out, thanks Rob.

I just found this home made DOC ISA board. Looks fairly straight forward and I would have given it a go if I hadn't found the DOC socket in my router

Note that to see a DOC you will need to program it with the right bios for the chipset. I just forn out when I had to add a /SIS5598 switch to see the DOC on a a SIS-based SBC.
You _can_ program the things though even if not seen as disk with the M-system tools specifying the window where it is on the bus.

( and, for the lonely waiting englishman - them DOCs finally in the mail).
