1. CD-Drive lettre shifted with USB install
Reply to this topic with quote Modify your message
Hello,

I've Warp 4 installed (with fix 15) on a portable PC on the C-drive.
I also have a data partition D.
My CD-drive is E.
After installation of the USB-basic & MSD drivers, my cd-drive lettre is shifted to G: !
How can I set it back to E?

Lines added in config.sys during installation of USB basic & MSD drivers :
(USB hostcontroller = Intel 82801DBM)

BASEDEV=USBUHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBUHCD.SYS /REQ:USBUHCD$,USBOHCD$,USBEHCD$
BASEDEV=USBHID.SYS
BASEDEV=USBMSD.SYS


Who can explain me these ?

[b]BASEDEV=USBD.SYS /REQ:USBUHCD$,USBOHCD$,USBEHCD$
BASEDEV=USBHID.SYS
BASEDEV=USBMSD.SYS /FLOPPIES:0

Hello,

OK you are right !
I made a typing error !
I had BASEDEV=USBD.SYS /REQ:USBUHCD$,USBOHCD$,USBEHCD$

But with adding /FLOPPIES:0
I do not have the possibility to acces my USB-floppy drive !
I've forgotten to mention it, but this was THE reason why I isntalled USB support !

Can you explain me why there is 3 times

BASEDEV=USBUHCI.SYS ?
and also one BASEDEV=USBEHCD.SYS
and the USBOHCD$ in the BASEDEV=USBUHCD.SYS /REQ: line?

Regards,

[b]
BASEDEV=USBUHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBD.SYS /REQ:USBUHCD$,USBOHCD$,USBEHCD$
BASEDEV=USBHID.SYS
BASEDEV=USBMSD.SYS

I have found a part of the answere :
When you look with pciscan, you find some usb host controllers. Well you have to enter as mutch as it is there !

For the moment I am looking how I can shift back my CD-driver letter to E.
With entering the USBsupport, there is a new device E (and sometimes a F) created. It shift my cd to E (or F). I want to have first my CD and afterwarts the USB-devices. (remember : I have also a USB-floppy)

Regards,

Sorry, but I don't think there is a way. The drivers involved (USBMSD and whatever allocates fixed drive letters) allocates the letters in a defined order, and, I don't know of a way to change this. LVM can change the partitions on the hard-drive, but, I don't think it works on the USB drives. And, I'm sure it won't work on the floppy or CD.

This general problem (adding drivers/partitions changing the CD-drive letter) is why I decided a long time ago to use RESERVEDRIVELETTER to set the CD drive to X on all my systems. I've even modified my OS/2 install diskettes to do this.

... with the following entry in your CONFIG.SYS:

RESERVEDRIVELETTER=R

With this entry your CD-ROM will be set to S: and kept there !!
