I am finishing up my BIOS and was optimizing the Warm Boot code, when I remembered I was reading in the entire CCP and BDOS when I warm booted. This was because Andy Johnson-Laird says in his book on Bios programming that some programs will overwrite the BDOS too. Unfortunately, to accomplish this feat of reading in the BDOS I also reinitialize the BIOS jump table (the CCP and BDOS don't fit into an even number of 1024 Byte sectors, after you subtract the 25 128 byte sectors on the first track.) I know that the BYE program really dislikes having the BIOS table, and specifically the warm boot vector overwritten, and since I could save much code by only reading in the CCP the Question I pose is as follows : Do you know of 1 or more useful programs that expect the warm boot to reload the BDOS as well as the CCP? Thanks in advance, a reply of "Yes, FOO.COM" is sufficent but more elaboration is encouraged. -- -- Chuck - - - D I S C L A I M E R - - - {ihnp4,fortune}!dual\ All opinions expressed herein are my {proper,idi}-> !intelca!cem own and not those of my employer, my {ucbvax,hao}!hplabs/ friends, or my avocado plant. :-} ARPAnet : "hplabs!intelca!cem"@Berkeley
