Bochs

[chrisa128]

Sorry, I couldn't find this anywhere on the forums.

Is there a way to get BOCHS to read a floppy disk direct instead of making a image all the time.

Thanks in advance...

Yes - modifiy your bochsrc to contain those lines:

floppya: 1_44=/dev/fd0, status=inserted
boot: a

Note that is specially for Linux

PS: I can't really believe you couldn't find that anywhere

[chrisa128]

I need to be able to do it under windows...

All I could find was questions asking what different errors meant, Though I only went back as far as October....

If you download the latest version for windows and look in the bochs folder you'll find an well documented sample file.
From the bochsrc-sample.txt from version 2.0.1:

Code: Select all

#=======================================================================
# FLOPPYA:
# Point this to pathname of floppy image file or device
# This should be of a bootable floppy(image/device) if you're 
# booting from 'a'.
#
# You can set the initial status of the media to 'ejected' or 'inserted'.
#   floppya: 2_88=path, status=ejected             (2.88M 3.5" floppy)
#   floppya: 1_44=path, status=inserted            (1.44M 3.5" floppy)
#   floppya: 1_2=path, status=ejected              (1.2M  5.25" floppy)
#   floppya: 720k=path, status=inserted            (720K  3.5" floppy)
#   floppya: 360k=path, status=inserted            (360K  5.25" floppy)
#
# The path should be the name of a disk image file.  On unix, you can use
# a raw device name such as /dev/fd0 on Linux.  On WinNT and Win2k, use
# drive letters such as a: or b: as the path.  Raw floppy access is not
# supported on Windows 95 and 98.
#=======================================================================
floppya: 1_44=/dev/fd0, status=inserted
#floppya: file=../1.44, status=inserted
#floppya: 1_44=/dev/fd0H1440, status=inserted
#floppya: 1_2=../1_2, status=inserted
#floppya: 1_44=a:, status=inserted
#floppya: 1_44=a.img, status=inserted

note the 2nd line from the bottom:
#floppya: 1_44=a:, status=inserted

Oh, what a shame! ::)

Maybe if you told us what happened when you tried it? Error messages, etc.

[chrisa128]

Floppy light flashes and then I get...

Boot from Floppy 0 falied
FATAL: Could not read the boot disk

Hi,
could be a problem with you boot code
suggestions:-
1. start your boot code with a jmp
i.e
[org 0x07c00]
jmp start
db ..........
db........
..........
.......
start:
.............
..........

2. End boot code with signature
i.e
times 510 - ($ - $$) db 0 (or something like that, check NASM docs)
followed by
dw 0xaa55
or
db 0x55
db 0xaa

post your code if you still get errors.

[chrisa128]

I am using GRUB as my bootloader, it also boots when I actually make an image but I don't want this extra work.

[Whatever5k]

This happens to me in Linux if I am not root. Make sure you are an administrator

[chrisa128]

There is no Administrator under Windows ME.

Maybe I will install Windows 2003 Server tonight but that is something I am not looking forward to

[Whatever5k]

Change the floppya line in your bochsrc file to this:

floppya: 1_44=1.44, status=inserted

Don't know if this will change something, but never mind

[chrisa128]

No effect at all...

Bochs can only directly read the floppy from Win2k/XP or *nix. Win9x/M-E won't work.
