Same as any bootable USB disk. Partition the USB disk, mkfs, rsync bootable filesystem contents, install boot loader. As follows: 1) Partition table looks like this: Disk /dev/sdc: 7996 MB, 7996440576 bytes 224 heads, 56 sectors/track, 1245 cylinders Units = cylinders of 12544 * 512 = 6422528 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 * 1 1245 7808612 83 Linux NOTE: you need to repartition with -H224 -S56 (or whatever) because I see some USB disks come with random heads and sectors settings. NOTE2: note "boot" flag 2) mke2fs -j /dev/sdc1 as normal, mount /dev/sdc1 /mnt/dst 3) rsync -av /triumfcs/mirror/SL/6.1/x64_64/os /mnt/dst (same contents as http://ftp.scientificlinux.org/linux/scientific/6.1/x86_64/os) 4) directory "Packages" is probably not needed 5) rsync -av .../SL-61-x86_64-2011-11-09-Everything-DVD1.iso .../SL-61-x86_64-2011-07-27-Everything-DVD2.iso /mnt/dst 6) cd /mnt/dst, setup "extlinux" (since the original uses isolinux). I use extlinux, mbr.bin, menu.c32 from extlinux-3.86. 6a) cat mbr.bin > /dev/sdc, ./extlinux -i . (notice the dot) 6b) extlinux.conf is a copy of isolinux.cfg with "vesamenu.c32" replaced by "menu.c32" from extlinux-3.86 7) umount /dev/sdc, try to boot it. > >I am making an SL6 installer for use on machines located where internet > >access is physically impossible, so is there a solution or workaround? > > > > There is a solution to this but I need to know the answer to the > above question. Ideally, I would like the installer run from the "Packages" directory rather than the DVD iso images. -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
