It's not Mandrake.  It is a 32M DiskOnChip in a standard Dual-In-Line Pack 
frequently used in BIOS storage though the BIOS is usually a 2M EEPROM.

Using some of the prebuilt stuff from www.linuxbios.org, and adding in a few 
things, I have built a ROM image of linux kernel 2.4 compiled for a specific 
Board, with FramebufferX, Python, ROX, and PointlessWM.  I am working on a / 
image for HD that will load the rest of the system.

What about the BIOS?  Well there isn't anything but linux and you need a 
password to boot, and it is hardwired in the DOC in an /etc/passwd 
(non-shadowed) file which is overtaken when / is mounted from disk.

The DiskOnChip is available here and there if you look hard for about $75 in 
single quantities including shipping.   Boards with DIP Bioses are getting 
harder to find, though, and you MUST compile the kernel for the board.  
Furthermore there is an extra-scary step in flashing the DOC, because you 
have to lever up the BIOS chip you booted with to make the kernel image and 
swap in the DiskOnChip--Yes, the BIOS EEPROM IS _REALLY_ hot-swappable, but 
if you make a mistake you fry many things including possibly yourself.


As for a rescue CD--well none is necessary so the linuxbios is set up NEVER to 
boot from CD or from floppy, only from itself, and then to seek a loadable 
full linux system.

On the first board I used, which was unfortunately a real cheapie, I booted 
linux with framebuffer X in about 5 seconds.  Now the second board is being 
readied, and I have to wait til I have a job for funds to complete the 
project, (need DDR and Processor and case, cause the last one was sold....)
