Pete Batard	8fb602b8ee	[mbr] use 80x25:16 text mode rather than 640x480:16 VGA mode ... * This should produce the same output while improving compatibility with systems that have a broken VGA implementation. * Also fix an LD error with newer gcc toolchains.	2022-07-04 15:08:55 +01:00
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	98c630d81a	[mbr] finalize protective message MBR ... * Note that msg.txt uses codepage 850	2020-02-19 18:49:39 +00:00
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
