How to access Hard disks bypassing the int 13h function calls
I am developing a small software that needs to access hard disk for data access. I will be booting directly to the software through floppy disks. So to access data from hard disks, I need to read sectors from HDD. The BIOS fn call int 13h, has limitations, coz even after putting the max values for head, sector and cylinder, I can go upto 8 GB of data. I need to make it work for larger disks, like 200 GB or more. Can anybody tell me whether there is some other way to access Hard disk and read sectors other than the BIOS int 13h call......
There wont be any operating system fns to call, since i will boot directly to my software from floppy instead of booting into OS.
Can anybody please help....
