Syslinux - Feb 2003 - Help bypass broken bios - el torito ???

Hi,

My problem is not uncommun, I have an old machine I'd like to use as a
linux  internet FW. The  Bios is old and does not let me boot from an el
torito bootable CD( 1998 PC) 

The CD's OK on other machines, boots fine 

Is there any way to get 

. isolinux on floppy, 
. when PC read floppy, isolinux tell it to boot from the /dev/hdc
device, 

all bootfiles are in /isolinux  on the CD (SENTRY-FIREWALL CD) 

I have looked around the net but didn't find relevant HOWTOs 

Thanks

Isn't this what the original syslinux is for ? :)

You could of course try and use Syslinux to Boot a Kernel and Initrd 
from floppy (Then Linux is running and can start using the CD), but I 
don't know if the needed things fit onto a disk (Syslinux, Kernel, 
initrd). It would of course be a big change in the way how your 
Sentry-Firewall CD is booted, but it might be possible to do so...

Hi,

I create a boot cd-rom with isolinux.bin following the instruction:

isolinux.cfg like as:

label rescue-linux
    kernel vmlinuz

the kernel vmlinuz is into /boot/, while isolinux.bin and isolinux.cfg are
into /boot/isolinux/

I typed the command

mkisofs -o rescue.iso -b boot/isolinux/isolinux.bin -c
boot/isolinux/boot.cat ..ETC.. /mnt/disk/iso

where isotree is into /mnt/disk/iso

and I get a iso image correctly.

After I write a CD-ROM with Nero.

Thanks, Alessandro
