Re: [Freedos-user] Problem installing FreeDOS together with Win98SE using metakern

Hi again, Robert

I know my problem was confusion between MBR and the boot sector.
But anyway, fdisk and bootmgr should return the same data...

Re: [Freedos-user] Problem installing FreeDOS together with Win98SE using metakern

[Anton Shepelev]

Hi again!

   Dear, Bernd, everything had been fine  (paths  and  filesizes)
   but  one  thing:  fdisk  and  bootmgr  were  returning   wrong
   bootsector dumps!

   I got it back to Win98SE, and invoked bootfix.  Unfortunately,
   bootfix returns everything in a text (ascii) format, so I  had
   to use FreePascal (from the FreeDOS distro!) to write a little
   program that  read  the  bootfix's  output,  "parsed"  it  and
   outputted the binary bootsector image to another file.

   Then I did everything as before and it worked (from the second
   attempt for some reason, maybe I had made a typo somewhere).

   .. I had spend quite a lot of time trying to figure  out  what
   was wrong, so I think this  tip  (to  use  nothing  else  than
   bootfix to get the bootsector) should be incorporated into the
   FreeDOS installer's howto and/or metakern's manual.

   .. And bootfix should be endowed with an option to output the
   bootsector in the plain binary format.

Many, many thanks
Anton

Start getting back to the original Win98 bootsector. You can write this 
mail, this you got internet access,
thus you can get a Win98 bootdisk from www.bootdisk.com.
Simply do SYS C:
(you might want to prefer to do ATTRIB + R C:\MSDOS.SYS first though as 
that might get overwritten otherwise).

I think we got some versions of SYS for that (3.5, from unstable kernel 
versions), but also BOOTFIX program for example
http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/disk/bootfix14.zip
Be sure to be at C:\ before running the program.

be sure to have exact paths ( C:\METAKERN.SYS for example instead of 
METAKERN.SYS) and check filesizes. Metakern.bin is 1512 bytes, 
Metaboot.bot 256bytes, windows bootsector dump also 512 bytes,
thus resulting in a C:\METAKERN.SYS of 2560 bytes. Your SYS commands are 
correct though there's the option of using /BOOTONLY to prevent any file 
copies.
Are you sure your bootsector filenames are 8 characters? looks like 9 to 
me (bm win 98 se)

It should work, let us know if you're able to get back to original 
situation (win98 booting) and if you run into trouble again.
