Sirs,
   Thanx for the suggestion of dos32a .But it uses the
DOS-extenders such as int 31h and int 64 ax=0xDE00
ect. 
But my idea is, as per Intel doc�s part �3,which
suggests about mode switching from real mode to pmode
,setting up IDT , LDT �.. Etc. I am looking at pmode
programming for setting up the cr0 registers,LGTR
instructions ,etc from google message board and other
sites. 
OK,
A  beginners idea(from me):
1)Linux made the boot image at the time of boot
process itself.(I don�t have the Linux src ) . if not
then,
In the kernel.asm at kernel_start: a switch to pmode
(after setting up the needed structures).But pmode
interrupt should be taken care by the structure IDT.

2)With out modifying any of the code  ,as Mr. Bart
said , programming for VCPI , DPMI.
All the above are very easy to talk but coding part??.

THANX
