Thanks to Icecube's (and others') pointers

I can successfully create and use .igz files for booting in UBCD411..... thank you
A lingering question from this last post is using multi-image bootdisks as either a set of .img files or else one .igz
Edited my c:\ubcd-extract file for remastering using a directory structure of
Quote:
\boot
\custom
...
\menus
bootdsk1.cfg
bootdsk2.cfg
bootdsk.cfg
defaults.cfg
...
...
\oldms
wnt4d1.img
wnt4d2.img
wnt4d3.img
...
**** Note that the previous \fat16 was changed to \oldms for this modification and remastering. Should make some sense for all this!
My current c:\ubcd-extract\menus ..\bootdsk.cfg and ..\bootdsk2.cfg contents are
..\bootdsk.cfgCode:
MENU INCLUDE /menus/defaults.cfg
LABEL back
MENU LABEL ..Go back to previous menu
KERNEL menu.c32
APPEND /menus/main.cfg
LABEL bootdsk1
MENU LABEL Freeware and Open Source Software Boot Disks
KERNEL menu.c32
APPEND /menus/bootdsk1.cfg
LABEL bootdsk2
MENU LABEL Non-Free Boot Disks
KERNEL menu.c32
APPEND /menus/bootdsk2.cfg
..\bootdsk2.cfgCode:
MENU INCLUDE /menus/defaults.cfg
LABEL back
MENU LABEL ..Go back to previous menu
KERNEL menu.c32
APPEND /menus/bootdsk.cfg
LABEL msdos622
MENU LABEL MS-DOS 6.22 Boot Disk
KERNEL memdisk
APPEND initrd=/oldms/dos622.igz
So how would I use the above setup to try booting up using the set of wnt4d# images?
Will a bootable multi-disk OS like this automatically read the second image or does a prompt for disk#2 appear?
If a prompt does appear requesting to insert the second floppy disk, would I simply be able to type in something like 'a:\wnt4d2' or maybe 'a:\oldms\wnt4d2'

If the former capability exists of automatically reading multiple boot images, then could I create a zipped 'wnt4d.igz file as written in the section 'Question: How do I edit files with the .igz extension? How do I create my own .igz files?' at
http://www.ultimatebootcd.com/faq.html 
If this is possible, then of course I'd have to edit the c:\ubsd-extract/menu\bootdsk2.cfg file to something like
Code:
LABEL msdos622
MENU LABEL MS-DOS 6.22 Boot Disk
KERNEL memdisk
APPEND initrd=/oldms/dos622.igz
LABEL wnt4
MENU LABEL MS-Windows NT 4.0 WS Boot Disks
KERNEL memdisk
APPEND initrd=/oldms/wnt4d.igz
Thanks much again for a reply here
