In linux we mounted /dev/sda1.  There is no DOS on that computer.

I recall something about this.

I don't know.  I think he did what he usually does to use it in 
Windows.  Should it be recognized as mass storage?

I will look that up.  Do you want to include that device in the next 
edition?

So this boot disk is not likely to work with all usb storage devices?

What counts as unusual?  So far it supported two out of four USB card 
readers without recompiling, and one memory stick and one camera, and not 
the USB PDA (but that might also need serial.o).

Can you also include this /dev next edition?

I will try that next time I get near a USB printer.

Hitting ] makes the image smaller (more of it fits on the screen).

I only tested your new zgv on Matrox and S3Trio3D (both vesa 2.0).  I 
think some vesa 1.2 cards don't - S3 Trio64V?  Cirrus?

I posted earlier about svgalib and various PCI video cards.

To boot with your 1-floppy linux in FB mode would I need to edit 
syslinux.cfg?
