I tried the extended read as follows:
 struct grub_biosdisk_dap dap;
 grub_uint8_t buffer[2048];
 dap.length = sizeof( dap );
 dap.reserved = 0;
 dap.blocks = 1;
 dap.buffer = (grub_uint32_t) buffer;
 dap.block = 17;
 x = grub_biosdisk_rw_int13_extensions( 0x42, drive, &dap );

"drive" was still 0xe0.

However, all I get in buffer is 0's. I tried reading other blocks as
well (e.g. 0, 1...). Any idea if I'm doing something wrong?

Thanks!
