Actually do we have 32,256 bytes to use? I was wondering about sectors 62 & 63 (counting from 0). On my laptop (that had windows wiped the minute I got it), I notice that there is a MSWIN4.1 boot record in sector 63 (I think it actually flows over the next 2 sectors also). So can we generally use that? I.E. does grub provide all the functionality of that sector? Also sector 62 has the following? Is that BIOS suspend to disk info or something, or maybe something left over from the windos install? # dd count=3D1 skip=3D62 if=3D/dev/hda 2>/dev/null | od -Ax -tx1z 000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 >................= < * 0000c0 67 68 46 50 b6 96 ca 3e bb 35 eb 3d 32 54 4f 53 >ghFP...>.5.=3D2T= OS< 0000d0 48 49 42 41 00 33 00 00 00 00 00 00 00 00 00 00 >HIBA.3..........= < 0000e0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 >................= < * 000100 00 00 00 00 00 00 00 00 00 34 33 4d 35 33 36 38 >.........43M5368= < 000110 39 54 00 00 00 00 00 00 00 00 00 00 00 54 4f 53 >9T...........TOS= < 000120 48 49 42 41 20 4d 4b 32 30 31 38 47 41 53 00 00 >HIBA MK2018GAS..= < 000130 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 >................= < * 000200 --=20 P=E1draig Brady - http://www.pixelbeat.org --
