My previous question: "can syslinux on a USBstik also boot installations
on other USB devices ?" got no proper reply, so I'm now including more
background detail.
The new problem is that my 32bit partition of ETHOberon, only gives
a proper font-size under Debian7:DVDinstaller:rescueMode, since I'm
forced to use a laptop, after my previous systems were stolen.
Neither gnome nor Xcfe allow changing the 13786x786 resolution, altho'
M$ 8.1 does, so it's not a hardware limiation.
>From eg. /mnt/sr0/isolinux/rqgtk.cfg ==
label rescuegui
menu label Graphical rescue mode
kernel /install.386/vmlinuz
append video=vesa:ywrap,mtrr vga=788 initrd=/install.386/gtk/
initrd.gz rescue/enable=true -- quiet
it seems that the vital parameters which give the good <font size> are:
"video=vesa:ywrap,mtrr vga=788"
On the DVD,
/mnt/sr0/install.386 looks like:-
|-- gtk
| |-- initrd.gz
| |-- install.bat
| `-- vmlinuz
|-- initrd.gz
|-- install.bat
|-- vmlinuz
`-- xen
|-- debian.cfg
|-- initrd.gz
`-- vmlinuz
2 directories, 9 files
and /mnt/sr0/isolinux looks like:-
|-- adgtk.cfg
|-- adtxt.cfg
|-- boot.cat
|-- dtmenu.cfg
|-- exithelp.cfg
|-- f1.txt
|-- f10.txt
|-- f2.txt
|-- f3.txt
|-- f4.txt
|-- f5.txt
|-- f6.txt
|-- f7.txt
|-- f8.txt
|-- f9.txt
|-- gtk.cfg
|-- isolinux.bin <-ISOLINUX 4.05 20121210

Q1.
Can the TC-64bit /boot/isolinux/isolinux.bin =ISOLINUX 4.05 0x4f92e181
system be given an entry which will boot the 32bit Slackware
installation on partn4 of another divice [USB driven disk] which
lookslike:-
Disk /dev/sdc: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdc1 * 1 88 706828+ 83 Linux
/dev/sdc2 89 358 2168775 83 Linux
/dev/sdc3 359 763 3253162+ 83 Linux
/dev/sdc4 764 21161 163840866+ 83 Linux <-ETHOinstltn
Q2. Can syslinux be installed to this 500.1 GB device, without messing
the existing sdc2,3,4; and also be able to boot installations on OTHER
32bit USB devices, plus 64bit TC ?
== TIA
