Problem with BOOT FLAG !!!

[r00t the LiNuXeRRR]

        I need to boot Linux, DOS and Win'98. I made the partitions and I
put an boot flag for DOS and Win '98, but the sistem is booting from the
first partition with boot flag. My partition table:

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1             1       254    512032+  83  Linux
/dev/hda2           255       286     64512   82  Linux swap
/dev/hda3  *        287       289      6048    6  FAT16
/dev/hda4  *        290      1023   1479744    b  Win95 FAT32

How can I make to boot from the partitions with Win '98 and DOS? If you
have an ideea please write to me.

Best regards,
