You don't have to PXE boot to use memdisk - you can reboot into a memdisk 
image from Linux (or Solaris 10 U1 or later - hello GRUB!). The main 
problem is booting back into your main OS after you're done with DOS. The 
nasty scheme we used was:

move /boot/grub.conf to /boot/grub.main
create the memdisk default /boot/grub.conf
reboot
after the dos installs are done, use LTOOLS (ext2/3,reiserfs for DOS) to 
rename grub.main to grub.conf
reboot

For Solaris you'd need to have a boot partition that you can modify from 
DOS, so FAT, ext2/3, or reiserfs should work (you'd have to use LTOOLS from 
Solaris as well as DOS for the latter).

Another option is to maintain a real DOS partition and change the active 
partition back and forth
