Hy, i'm trying to use UDPCast for installing 20 PC boxes in FineArts Universiti at Barcelona, the problem I've found i think is no such difficult to resolve, but I'm not able to. (head to short? :-) ). Ok.lets go 1. Bootdisk failure in kernel booting: enabled ExtINT on CPU 0 ESR value before enabling vector:00000000 ESR value after enabling vector:00000000 using local APIC timer interrupts calibrating APIC timer .... CPU clock speed is 1799.7757MHz .... CPU hosts bus clock speed is 0.0000MHz CPU:0, clocks:0, slice:0 ------------kernel stops here ------------ bios technical specifications BIOS PT84520A.86A.0010.P5 (for the sender) all machines have exactly same HW conf. & same disk Intel Celeron (R) CPU 1.80 GHz BUS 400 MHz MEM 266 MHz . At this point I'm thinking to try and make a boot disk able to run on this machinnes and then use udpcast for it. Question? How I make this bootdisk? the motherboards don't allowme turn off ACPI (i think its that the problem) so I don't know anyway to get aout of it. Thanks for any help :) oH!, my name is JACI or jazz. thnks
