Post subject:  Problems with tools booting from usb

Hi, I've been using UBCD since it came out. I love the fact I can boot from usb but I'm having an issue with anything that seems to run freedos. It seems like it is looking for the CD. I'm fairly new to booting off usb drives. Thank you for the help and sorry if this has been posted but I could not find it.

Are you using UBCD50RC1?

You can take a look here (work around):
viewtopic.php?t=2159

Can you post the output of the command 'drd'?

I went to the post above I don't know how to rebuild an .iso. I tried to just edit the .cfg file but that didn't seem to work.

drd output:

C-P invalid
Q writable
R-S inaccessible
U-Z invalid

Thanks for the help

Did you get the ubcd50RC1_dos.iso from:
http://ubcd.stopspazzing.com/downloads/ubcd-dos/
And did you place it in /ubcd/custom/ of your USB stick?
(You don't need to rebuild the iso if you boot from USB)

You need to boot this entry in the submenu 'User-defined Tools" ==> "Boot DOS apps of UBCD50RC1".

No I didn't download that I thought it was just another copy of the UBCD.

So, if I understand correctly just copy that .iso I just downloaded to the /ubcd/custom/ of the USB stick.

I don't understand what yo mean by "boot this entry"..

I'll also go back to the other post and after adding the .iso image to the usb stick.

Thank you for your help..

Icecube is this a issue with FreeDos not finding/mapping the CD drive properly? I understand the concept of the workaround just curious.

Yes, it is.

I hope Victor knows a way to fix the problem.
Maybe when you step trough the FreeDOS booting part manually (choose which USB driver to use), it may work. The default won't work for everybody, it seems.
There a new USB drivers for DOS (not in UBCD50RC1), maybe they can help:

I have a system without cdrom drive (being doomed to usb boot), and the cdrom.bat always fails. I think you preload the cdrom driver in your iso, and no autodetection is needed from FreeDOS. Is it correct?

What do I have to change to skip FreeDOS autodetection for all other menu entries (which require it), because the main menu is nicer.

Post subject:  fdubcd.img.gz

I've copied fdubcd.img.gz from your iso into ubcd/images/, but it still don't work.

No, you don't extract fdubcd.img.gz from IceCube's ubcd50RC1_dos.iso.

You put the entire ISO in c:\ubcd-extracted\ubcd\custom.

Then you add the following in c:\ubcd-extracted\ubcd\custom\custom.cfg:

Code:
LABEL ubcd50RC1dos
MENU LABEL Boot DOS apps of UBCD50RC1
LINUX /boot/syslinux/memdisk
INITRD /ubcd/custom/ubcd50RC1_dos.iso
APPEND iso raw


Then boot UBCD, and select "User-defined Tools" ==> "Boot DOS apps of UBCD50RC1".

The idea is this creates a virtual CDROM drive and boot the FreeDOS image within it. Since it's a virtual CDROM drive, FreeDOS will have no problems mounting the drive.

I will be trying this method and gathering feedback in UBCD V5.1.

Sorry. I was not clear. The IceCube's method worked. I just tried to move the changes from his iso to the original stuff :-)
