    How can I check if a motherboard can boot a Cdrom with a 2880
    img bootdisk ?
    Or even a 1722 one ?
    I'm building a router, and want to know how big an image my
    TX97 can boot.

    An antique like that almost certainly does not support cdrom or fdd boot
    images greater than 1440...

    Does not work that way, since a CDROM bootsector is 2048 bytes,
    while a floppy bootsector is 512 bytes. They are fundamentally

    Considering ED floppy drives are from the early nineties
    (http://simple.wikipedia.org/wiki/Floppy_disk says 1991), so why
    wouldn't a TX97 have support for those in the BIOS?

    I'm almost certain I installed Linux on my old system with Asus T2P4
    motherboard, by just putting a 2.88 boot floppy image on a CD. The
    rest of the installation was downloaded from the net.

    To the original poster, I'd go ahead and try the 2880 bootdisk image.

    As a follow up, I built a 1680 floppy, made it bootable with
    syslinux. tested it, when I was sure it was working, wrote the files
    to a iso file using mkisofs/isolinux bootloader.
    I had trouble with 1722 floppies, lots of bad sectors, not
    always though .... bad floppy drive ?
    Resume , always boots 1.44 and 1.68, and sometimes 1.72. No
    2.88 drive here to test, and I can't figure out how to make a 2.88
    image bootable without the hardware to write it to a disk, though it
    IS possible (but too complicated for me) according to Google.

    Not necessarily. Maybe just operation grossly out of spec.
