    LTSP on Laptops

    I wanted to get LTSP to work on an old Laptop (Toshiba Satellite 4030CDT). It doesn't have on-board Ethernet, it has a Xircom RealPort CardBus Ethernet 10/100 (RBE-100). Using this Ethernet adapter requires the PCMCIA subsystem be initialised first, so a 16 KB boot rom (off floppy say) wouldn't do it.

    The answer was to use the 1.4 MB boot image from wireless_ltsp-3.0.5-i386.tgz on Sourceforge -- it contains a full 2.4.19-ltsp-1 Linux kernel and initrd, so the laptop boots from there rather than a 2.4.26-ltsp-2 image TFTP'd from the server.

    After initial Linux boot and pivot-root the laptop does try and load kernel modules from the server, and so it's a good idea to install ltsp_kernel-3.0.5-0.i386.rpm (also from SF).

    I'm only using the PCMCIA card ability, not the Wireless ability, yet ...
