How can I use CALL?
Posted: Mon Mar 10, 2003 12:00 am
STAGE1 of my bootloader loads at 0x0070:0x0000.
STAGE2 of my bootloader loads at 0x0090:0x0000.
There is a function in there (cputs) that I want to use in the STAGE2 bootloader.
cputs does use short jumps, but does that make a difference?
STAGE1 puts the pointer to cputs (Linear address) into a location in memory with some other variables.
STAGE2 reads the value into ax, (the value ends up being 0x7b0(the value is correct)).
How can I use CALL to run the function from STAGE2?
