Hi, I just succeeded in booting Linux on Fiasco. Just in case anyone is interested, here are the warnings I got while booting: (both packages are of 12/07/98, compiled under Linux) ----------------------------------- Welcome to Fiasco! DD-L4/x86 microkernel (c) 1998 TU Dresden - Dec 24 1998 linux_startup checking OFFS_TSS: ok, OFFS_TSS still 536 detect processorsetup_paging end linux_startup, calling start_kernel setup_arch sigma0 denies mapping of address 00001000 No kernel code/data sigma0 denies mapping of address 00002000 No kernel code/data [...] sigma0 denies mapping of address 00149000 No kernel code/data mb4 already requested 4m page received sigma0 denies mapping of address 00ccc000 No kernel code/data Memory end: 00ccc000 kernel info page mappt to: 00001000 root: rcvd 2, 424a25 Hmm, strange, that shouldn't happen anymore Root: null pointer deref in 5.3 at addr: 2 and eip: 424a25 (pte: 27) ------------------------------------- Then Linux tries to initialize the serial driver and stops because I logged this messages over serial cable. When I boot it without cable, everything works fine and stable, I just get *a lot of* wake_idle_if_needed: ipc failed messages, but this seems to be no problem. The only thing I`ve found that doesn`t work is XFree86, when I try to start it, the machine freezes with blank screen. Today I`ll try to get pcmcia running. Ok, now my questions :) 1) Are there any documents you suggest reading, besides the L4 Reference Manual? Any document would be of use, since I don`t have a clue on L4, but I want to play around with it. Is there anything like "L4 for dummies" ? :) 2) Is Fiasco capable of running multiple servers at once? I tried to start two instances of this helloworld-server, but it crashed immediately. 3) Is there a simple way to reboot the system after Fiasco startet? My Laptop has no reset button :) Ok, I`ve already stolen enough of your time, many thanks for being patient with me :) MfG Benjamin
