+It is good joke, at this moment I have only simple version of MBR to load
+image from HD, but only from track 0. HD have to have enough sectors per
+track for rom image.
+And small program in turbo-pascal to download image to HD.
+
+below is assembler code for MBR. Is writen for tasm and tlink. 
+If you have 512 bytes binary file with MBR code, then concat it with
+rom-image and download to hda. BUT NOT DIRECTLY !!!! You have to copy 
+partition table ( and NT signature ) to MBR and then download. BUT ONLY tO
+TRACK 0.
+
+Everything in your own risk.
+
+If I will have some free time, I will write some code directly to netboot.
