--- Quote from: Josepha on October 08, 2018, 05:50:03 AM ---Question 2: I noticed in example above the location of usb flash drive is hardcoded as hd0.1 in grub.cfg. Is grub file location persistent for removable usb/devices ? Is it possible the hd0.1 location may vary depending on which usb port and order usb devices are inserted at computer ? (My concern is that my TCL/usb flash drive may not work in other computers if hardcoding location of files).

I think we answered these questions at you're other thread..
http://forum.tinycorelinux.net/index.php/topic,22277.msg139447.html#msg139447

And where do you see a USB drive ID hard coded as hd0.1 ?? 

search --no-floppy --fs-uuid --set=root 196fcfb2-bd37-495d-b855-41f08201be7d
Will set this drive as root (1st drive)

waitusb=5:UUID="196fcfb2-bd37-495d-b855-41f08201be7d"
Will pause the boot process until this specified drive has initiated

tce=UUID="196fcfb2-bd37-495d-b855-41f08201be7d"/tc8-x86
This bootcode informs TC where to find the tce/extensions required by this boot.cfg entry.    In this case i changed the name "tce" to "tc8-x86", so this needs to be specified, otherwise not.

i like persistance
mount -o loop iso_path i use /iso/CorePlus-16.1.iso on 1st parition  /mnt/folder name i use /mnt/x
mnt/x will be read only copy it to i use /mnt/boot then i rname x in /boot to coreplus
rename the cde folder to tce in the i use /boot/coreplus


--- Code: ---menuentry "coreplus iso cde>tce  " {
   load_video
   insmod lvm
   insmod gzio
   insmod part_msdos
   insmod ext2
   insmod part_gpt
   set root='hd0,msdos1'
#  search --no-floppy --label A1EXT2 --set=root
    echo 'setting up isofile ...'
    set iso_path="/iso/CorePlus-16.1.iso"
#  search --set=root --file $iso_path
    echo 'setting up loopback'
    loopback loop (hd0,msdos1)/${iso_path}
    echo 'booting vmlinuz ...'
    linux (loop)/boot/vmlinuz iso=/mnt/sda1/${iso_path} loglevel=3 waitusb=5  showapps desktop=icewm  tce=sda1/boot/coreplus/tce noutc
    echo 'initrd ...'
    initrd (loop)/boot/core.gz
}
menuentry "coreplus iso syslinux memdisk cd>tce tab edit boot options  loglevel=3 waitusb=5  showapps desktop=icewm  tce=sda1/boot/coreplus/tce  " {
   load_video
   insmod lvm
   insmod gzio
  insmod part_gpt
   insmod part_msdos
   insmod ext2
   set root='hd0,msdos1'
#  search --no-floppy --label A1EXT2 --set=root
    echo 'setting up isofile ...'
    set iso_path="/img/CorePlus-16.1.iso"
#  search --set=root --file $iso_path
#    echo 'setting up loopback'
#    loopback loop (hd0,msdos1)/${iso_path}
    echo 'booting vmlinuz ...'
    linux16 /img/memdisk raw
    echo 'initrd ...'
    initrd16 /img/CorePlus-16-1.iso

}
--- End code ---

you can use the set root or search lines (that i # have disabled)
i keep my CorePluse-16.1.iso on first partion in /iso folder
i use both insod part_msdos & insmod part_gpt
