There are only 10 bits for the cylinder number in the arguments to the INT 0x13 calls (plus 6 bits for the head number). However, most today's SCSI BIOSes use the entire available BIOS address space, that is 1024 cylinders, 64 heads (some are over- cautious and use only 63), 255 sectors per track. This makes up for j@uriah 1546% echo 'scale = 2; 1024*63*255*512 / (1024*1024*1024)' | bc 7.84 GB bootable area. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
