Hi *, i use 3com PXE Util to load different images for installation. Thats what i do: 1) Format boot disk and "syslinux /dev/fd0" 2) Copy "bootlogo isolinux.bin linux message initrd isolinux.cfg memtest" from "/boot/loader" to diskimage using 3com PXE Util 3) Rename "isolinux.cfg" to "syslinux.cfg" 4) Generate PXE Menue and link the diskimage 5) Place diskimage and PXE Menuefile on tftp server 6) Link PXE Menuefile in dhcpd.conf This workes fine - i have done such images for SuSE 8.x, Redhat 8.x and 9.x for Debian 3.x and Fedora 1.0 - with SuSE 9.0 the Kernel panics when try to access the ramdisk, caused by the previous error: "Couldn't find valid ram disk image starting at 0". Files in image (and LDLINUX.SYS of course): 117523 Oct 20 14:53 bootlogo 5459309 Oct 20 14:53 initrd 14840 Oct 20 14:53 isolinux.bin 802 Oct 20 14:53 syslinux.cfg 1191629 Oct 20 14:53 linux 80324 Oct 20 14:53 memtest 490 Oct 20 14:53 message the initrd is original and unmodified version. load_ramdisk=1 wont change anything and got nothing to deal with the problem anyway (not 120% sure of this). I already replaced isolinux.bin with the latest version from kernel.org. I can reproduce the error on different systems. BTW, is there somebody out there using 3com PXE Util (except for RIS) ? Thanks, Felix.
