Problem booting Fiasco on Pentium IV
by Julian Grizzard 10 Nov '04

10 Nov '04

Hi, I was able to boot Fiasco on a PIII 450 Mhz, 128MB. However, I have tried the same procedure on a Pentium IV 2.5GHz, 1GB RAM and it does not work. I get to this point in the boot process and it stops: |RMGR: Stage1 | loading /boot/sigma0 | loading kernel /boot/main -nokdb -nowait | kernel at 00300000-0039d624 | detected new-style DD-L4(v2)/Fiasco | configuring sigma0: 00090000-00095000, start: 00090000 | reserve modules memory range: 00223000-0022d175 | starting kernel /boot/main -nokdb -nowait proto=0x101fa0 @ 0x00300aa0 | |Loading ELF image (kernel) at 0x303140 [entry 0xf0001000] I used all the defaults when building L4, rmgr, sigm0, and hello. Is there anything special I need to do when booting on an PIV? I also created a floppy disk and booted it on both the PIII and the PIV. It boots on the PIII but not on the PIV. Anyone have any ideas as to what my problem is? Here is my grub configuration: |title hello world | root (hd1,0) | kernel (/boot/rmgr -sigma0) | module /boot/main -nokdb -nowait | module /boot/sigma0 | module /boot/hello Anything else I can provide that would be useful? Thanks! -Julian

Hi, I just made a simple L4Env::Dice module to put in shape my thougths about this.. The implementation is in perl and there's no code :-) Best regards, erob

L4Env on freebsd
by granted14＠yahoo.com 03 Nov '04

Hi, Recently I had a few things that would need your opinions or advices.. Since dde is very hot, is it possible to have L4Env in perl5 or in any other kind of low-level langage? The reason is for not having to write very optimized L4 code in raw IDL format or in C, since I have pratically no expression with them*. I don't know how or if compilers like Dice or IDL4 currently play nice with dde_linux, nor if it could work with a hypothetic dde_to_any (kind-of) librairy**. Does implementing this in perl gives the ability to have a cool system in L4 (snesh), as with the Hurd or with L4-Linux, or elses? Best regards, Etienne Robillard * I guess -- it's like implementing L4 in any languages feels kludgy for me, with all respect to the sens of this word ;) ** Note 2: In dde-0.02 theres already headers for dde_linux. Are theses autogenerated or do someone cares for them ? I would love to see dde_lites.h or dde_freebsd.h :-) ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca

My adventures trying to boot L4Linux kernel + Fedora
by Tiago Jorge 25 Oct '04

25 Oct '04

hello again. I've downloaded from the L4Linux CVS the version that matches more with the kernel that my Fedora Core brings, 2.4.22. I've made make menuconfig and, as instructed, removed all thing that messed with the hardware himself(APM, ACPI, etc), make, make modules and make modules_install. I've made mkinitrd to make a initrd file. When i try to boot it, it gives-me this error (same in vmware and physicaly, but i've done it in vmware now to send the error) ================================================ Welcome to Fiasco(ia32)!

Building and Using the Fiasco µ-Kernel, new user
by Julian Grizzard 25 Oct '04

25 Oct '04

Hi all, I am just starting to look into the Fiasco microkernel for some research I am doing. This looks like a very neat project and you guys have done some great work! I have followed the build instructions located at: http://os.inf.tu-dresden.de/fiasco/use.html as a starting point and wanted to share the two problems I ran into. First, I could not get the "make config" to work on my gentoo system (gcc 3.3.4, make 3.80). This is what happened: $ make config make -C ./tool/config make: *** C-Compiler needs target arch. Maybe you mean HOST_CC. Stop. $ Not sure what the problem is. I noticed the message appears to be the contents of the ${CC_} variable in l4/mk/Makeconf. My work around was to compile on a redhat 8.0 box. Second, I had this problem when I booted the system: --init--------------------------------------EIP: f0010a0f jdb: Here is the grub configuration I used on the floppy (from http://os.inf.tu-dresden.de/fiasco/use.html): # this is /floppy/boot/grub/menu.lst title hello world kernel (fd0)/rmgr -sigma0 module (fd0)/main -nokdb module (fd0)/sigma0 module (fd0)/hello After digging around, I decided to change the thid line from "module (fd0)/main -nokdb" to "module (fd0)/main -nokdb -nowait". Is this correct? It seems to be working. Thanks! -Julian

Problem building L4Linux

22 Oct '04

Like i said in previous emails, im trying to boot the Fedora Core 1 that i have in my disk with the L4 u-kernel. I've done a classic config stuff... i went to get the Fedora kernel config file and put it like.config in L4Linux kernel directory. I've configured the l4 options i tried to built it. I'm trying to build the 2.4.22 L4Linux kernel. The error that gave me it's here... -D__KERNEL__ -I/root/l4linux-2.4/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -g -DLINUX_ON_L4 -pipe -mpreferred-stack-boundary=2 -march=i686 -nostdinc -iwithprefix include -DKBUILD_BASENAME=apm -c -o apm.o apm.c apm.c: In function `apm_bios_call': apm.c:626: warning: implicit declaration of function `loadsegment' apm.c:626: error: `fs' undeclared (first use in this function) apm.c:626: error: (Each undeclared identifier is reported only once apm.c:626: error: for each function it appears in.) apm.c:626: error: `gs' undeclared (first use in this function) apm.c: In function `apm_bios_call_simple': apm.c:679: error: `fs' undeclared (first use in this function) apm.c:679: error: `gs' undeclared (first use in this function) apm.c: In function `apm_init': apm.c:1984: warning: implicit declaration of function `set_base' apm.c:1984: error: `gdt' undeclared (first use in this function) apm.c:1986: warning: implicit declaration of function `_set_limit' make[1]: *** [apm.o] Error 1 make[1]: Leaving directory `/root/l4linux-2.4/arch/l4/kernel' make: *** [_dir_arch/l4/kernel] Error 2 Could somebody help me Thaks in advance Tiago

The file name doesn't sound likes it's a rd. this file is a initrd file to the L4Linux kernel. What i'm trying to do is boot the Fedora that i have in the disk using the new kernel. But i think i have overcome the L4 problems. Now is just plain Linux Kernel problems (i think)... but tks for the help anyway. cheers Tiago <http://os.inf.tu-dresden.de/%7Eadam/>

Problem booting L4Linux 2.4 + L4Env (Part 3)
by Tiago Jorge 21 Oct '04

21 Oct '04

ok... i think this is my last email today for this to work... :) I can now boot L4Linux with the drops RAMdisk and everything goes all right in VMware and in real hardware. But now i have a few more questions: 1. I'm trying to boot the Fedora Core 1 that i have in my disk with L4Linux kernel but i haven't found a way yet. Like we say here in portugal, i've been trying to "hammer" a solution, but didn't worked out. my grub.conf looks like this: title Fiasco + L4Linux root (hd0,0) kernel /fiasco/rmgr -sigma0 task modname "vmlinuz" module modaddr 0x02000000 module /fiasco/main -nokdb -nowait -serial_esc -comspeed 115200 -comport 1 module /fiasco/sigma0 module /fiasco/vmlinuz no-scroll no-hlt l4irqack=linux root=/dev/hda5 module /fiasco/2.2.27.img <===== i'm doing this beacause i can't use initrd is this the right way to do it? Im i missing something? he says that can't find a init and even when sometimes he loads the img, it crashes while loading it from disk. /dev/hda5 is my / partition. 2. Is it mandatory in L4Env boot to have the tftp server? can't i boot it from disk? Ok... i'm beeing very annoying for today, but i'll write a tutorial in the end :))) Thaks in advance Tiago
