Hi.

Can someone at least reply? If noone actually knows anything, a few responses would be comforting. If anyone has any ideas on how I can switch disk images when I need to, that would be great.

A scientist claims in court that the reason he ran a red light is that,
due to his speed, the color was blueshifted till it appeared green.
Needless to say, the charges of running the red light were dropped and
he lost his license for speeding excessively.

Just had to respond to your plea. I have the same problem when I send out a request for help and get no response. Anyway, back in the eighties, the BIOS was changed to allow for computers with only one floppy to fake switching to a non-existent b: drive. My suggestion to you is to set your boot program (grub, etc.) to allow for a true DOS boot (Freedos/4dos in my case) and read in your floppies (sounds like a program install). Then access the data from Linux, if that's your choice. Just another way of looking at the problem.

Hi there,
Thinking about your problem I just tried this, and it seemed to work

In Linux

Copy contents of disk1 to /tmp/disk1 Copy contents of disk2 to /tmp/disk2 Copy contents of disk3 to /tmp/disk3 Copy contents of disk4 to /tmp/disk4

then cd /tmp

ln -s disk1 a

Now in DOS do
lredir a: linux\fs/tmp/a

start install in DOS, when prompted for disk change do the following in Linux

rm a
ln -s disk2 a

back in DOS press OK, or whatever to signal disk has changed

and repeat until done

Hope that helps,

Andrew

==================== example ======================= ### Linux
cd /tmp
mkdir disk1 disk2
echo hello > disk1/hello.txt
echo there > disk2/there.txt
ln -s disk1 a

### DOS
C:\>lredir a: linux\fs/tmp/a
A: = LINUX\FS/TMP/A attrib = READ/WRITE

C:\>dir a:
Volume in drive A is /tmp/a Directory of A:\

HELLO TXT 6 04-06-08 7:45p
1 file(s) 6 bytes
0 dir(s) 2,147,450,880 bytes free

### Linux
cd /tmp && rm a ; ln -s disk2 a

### DOS
C:\>dir a:
Volume in drive A is /tmp/a

Directory of A:\

THERE TXT 6 04-06-08 7:46p
1 file(s) 6 bytes
0 dir(s) 2,147,450,880 bytes free
