Here is a partial patch that I'm using to illustrate a few questions that I have. Looking at the gpllib write_sectors (com32/gpllib/disk/write.c) it looks like the allocated size is wrong; size is in sectors so we should adjust the alloc/memcpy by size*SECTOR. Also, comparing core/diskio.c it looks like the registers aren't even setup right. In the patch below I put an #if 0 around the

This patch introduces extra functionality to chain.c, mainly with reference to BPB adjustments, but not only that. It expects 3 small patches I sent earlier (they are included for easy reference, patches 1-3/4). The changes introduced are: 1) file and boot sector use separate options to control load address and jump address (if applicable). Options are as described below: *
