Pete Batard	2dd538b7cb	[core] fix MBR protective message overwriting the primary GPT ... * We distractedly chose to populate the message from our protective MBR for GPT/UEFI-only boot media into the 4KB that directly followed the MBR, which of course is space that is being used by the primary GPT. * This resulted on systems having to fall back to using the secondary GPT, which not all appear to be designed to do. * Alter the code to ensure the protective message is written at LBA 34, after the primary GPT. * Closes #1507	2020-04-13 17:05:33 +01:00
Pete Batard	bfbb9d2ed5	[mbr] replace gpt.S with a more generic msg.S ... * msg.S now reads an ASCII message (with escaped colour sequences) from the following blocks, which is both more flexible and allows for more content to be displayed. * Also adds Bochs testing to the MBR build facility	2020-02-19 14:23:42 +00:00
Pete Batard	0f57ed1684	[mbr] "Press any key to boot from USB..." ... * Adds an MBR to prompt the use about USB or HDD boot * If USB boot is not selected, an INT13h override is added to make the second bootable drive think it is first (0x81 -> 0x80) * USB drive BIOS index is left unmodified	2012-03-20 02:56:34 +00:00
