Hey Andy!

That was the same situation here until this past summer.  I could get compact
flash disks to boot off an ide adapter on all sorts of machines - especially
good on ye ol' 486's - and more recently with flash disks that plug directly
into an ide interface on a motherboard.  Matter of fact, this is the first boot
off such a drive - M-System's iDOC 64M - on the new PGA775 Intel board I
managed to liberate.  This is what shows regarding the disk;

    Probing IDE interface ide0...
    hda: M-Systems iDOC V1.01 030804, ATA DISK drive
    ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
    hda: max request size: 128KiB
    hda: 128128 sectors (65 MB) w/0KiB Cache, CHS=1001/4/32
    hda: cache flushes not supported
     hda: hda1

    /dev/ramdisk             35692     31232      2617  92% /


I have a pure 64-bit initrd on there mounting on /dev/ram0 which makes it run
like a screaming demon once it has loaded.  The exact same initrd is on a USB
flash disk and takes a helluva lot longer to load but runs as fast once it is
in ramspace.  As shown above it fits into a 36M space.  I have ones that are
less but they aren't nearly as mean as this one is.  /home is currently a
mounted sata drive partition as well as a chrootable development system.  I
need to install a 32-bit cross compiler on there which is penciled in for
tomorrow.

Awesome way to do this.

I've had problems with USB CD-ROMs in the past but I think this box should
handle it.  Am planning to try a DVD-ROM later and see if that works.  No
Firewire ... yet.  I saw a Firewire TV tuner that caught my eye but way too
much money, or at least more money then I am willing to part with just for TV. 
I have some ideas for it though, beyond TV, so maybe someday.

I did that with Slackware quite a few years ago.  Worked pretty good, far
better then floppies that is for sure.

Great idea.

Life is good,
Maurice
