Hello ! I am using the debug version of isolinux but it's verbosity doesn't help me... here is my booting screenshot : (from screen to paper and then to screen :-) -Starting, up DL = F0 -Loaded spec packet Ok, drive = F0 -Sector size appears to be 0800 -Loading main image from LBA = 00048399 -Sectors to load = 0004 -Loaded boot image, verifying... -Main image read, jumping to main code... -Root directory at LBA = 00000098 -isolinux directory at LBA = 000033B5 -About to load config file... -Configuration file opened... -boot: Then i wait until the timeout occurs : -Loading. -4000 -AX:0208 -BX:0200 -CX:0002 -DX:0000 -4000 -AX:0208 -BX:0200 -CX:0002 -DX:0000 ......etc It do the same if i type in the kernel's file name (kernel.img) Here is my isolinux.cfg : -PROMPT 1 -TIMEOUT 600 -DEFAULT Srv1 - -LABEL Srv1 - KERNEL kernel.img - APPEND initrd=initrd.gz root=/dev/ram0 - -LABEL Srv2 - KERNEL kernel.img - APPEND initrd=initrd.gz root=/dev/rd/0 As the tree i want to burn is about 1500 Mo big, i have used mkzftree to make it smaller : # mkzftree -z 9 uncompressed_root compressed_root then i have uncompressed the isolinux directory : # cd compressed_root # mkzftree -u isolinux uisolinux # rm -rf isolinux # mv uisolinux isolinux (The iso image i got is about 600 Mo big ! one CD for 1500 Go :-) I have checked that file in this directory were not compressed, and it is ok. I can do 'cat isolinux.cfg' for example, it is fully readable. I have also checked that files used by isolinux are at the begining of the image by passing to mkisofs the option '-sort isolinux/iso.sort' iso.sort contains the following lines : isolinux 200 isolinux/isolinux.bin 100 isolinux/isolinux.cfg 150 isolinux/kernel.img 50 isolinux/initrd.gz 25 Here is what i pu in the isolinux directory : bash-2.05a$ ls -ails isolinux/ total 6352 86651 4 drwxr-xr-x 2 root root 4096 08-09 19:30 . 213832 4 drwxr-xr-x 20 root root 4096 08-09 14:56 .. 86656 4 -rw-r--r-- 1 root root 400 08-09 14:11 sample.msg 86655 5084 -rw-r--r-- 1 root root 5192044 08-08 00:48 initrd.gz 86652 12 -rw-r--r-- 1 root root 9172 08-09 19:31 isolinux-debug.bin 86646 4 -rw-r--r-- 1 root root 181 08-09 17:59 isolinux.cfg 86645 4 -rw-r--r-- 1 root root 175 08-09 19:30 iso.sort 86654 1208 -rw-r--r-- 1 root root 1230215 08-08 22:21 kernel.img 86657 28 -rw-r--r-- 1 root root 25771 08-09 14:11 syslogo.lss bash-2.05a$ I have always the same dump of registers (AX, BX, ...) with 2 different machines - one with a MSI K7T266 PRO motherboard and an IDE CD - the other with a MSI K7D Master, DC-390U3W SCSI adapter The syslinux/isolinux version is 1.75 It would be very nice if you could help ;-) I suppose i did something wrong, but i don't know what ...
