[syslinux] Boot DOS through Pxelinux

[Joel C]

Thanks for your help. I decided to try a different approach by installing
another HDD, created a 3MB partition and installed DOS from a 2-floppy
set. Then I created a DOS image by:
 dd if=/dev/hdb2 of=dos.img
 When the system boots through PXE, however, I'm getting an error:
 ======================================
Loading boot sector... Booting...
 DISK I/O error
 Replace the disk, then press any key
 ======================================
The pxelinux.cfg/default looks like:
 Label foo
kernel memdisk c=1 h=22 s=37
append initrd=dos.img
 =====================================
 I'd appreciate any suggestions/help.
 THanks,
 Joel
