Hello, I am using pxelinux.0 included in syslinux V3.11. A DOS floppy image is loaded via TFTP and boots fine as long as a physical floppy is in the system and enabled in the CMOS settings. We also use systems running on the same platform that don''t have physical floppy drives. In this case the image is loaded, but I receive the message "Operating system not found" as soon as the image is trying to boot. My "default" in pxelinux.cfg is: default boot prompt 0 say booting... label boot kernel memdisk append initrd=multinet.imz The LSM file of V3.11 said: "MEMDISK: Try work around a bug on some BIOSes when no physical floppy disk is present in the system. " Seems that the problem still exists. The problem occurs on all platforms I use. One is running on a P3 with VIA chipset and Phoenix - Award Bios V6.00PG, the other one is running on a PentiumM with Intel chipset and Phoenix - Award Bios V6.00PG. Both systems behave the same. If the physical floppy is present and enabled there is no problem. As soon as I set the floppy to "None" in the CMOS settings, the image does not boot anymore. I also tried to load the image as a harddiskimage. It did not help. Best regards Frank _____________________________________________________________ Show the world your Caribbean soul.
