Eric-Paul Ickhorn	44ca45e8f1	Finish up GDT, get linear address space working The GDT is now finally set and produces a linear address space. Execution continues at 'stage2_true_entry'.	2024-07-06 00:12:07 +02:00
Eric-Paul Ickhorn	0d49245a60	Delete GDT-related files This commit deletes the gdt.asm for the i386 architecture as it was quite buggy in that state. In a short while, the real GDT code which works is going to be committed.	2024-07-06 00:12:06 +02:00
Eric-Paul Ickhorn	993864e364	Save progess, then delete GDT for rewrite This commit saves the progress made on the GDT; the files are deleted quickly thereafter as the code was quite buggy.	2024-07-06 00:12:06 +02:00
Eric-Paul Ickhorn	83eb29d55c	Try to fix GDT; unsuccessful This commit just existed because of a misunderstanding leading to the belief that the GDT was finally working; it wasn't though.	2024-07-06 00:12:06 +02:00
Eric-Paul Ickhorn	c3f2c7fbfc	Intermediate commit to add GDT In this commit, it was tried to set a linear GDT. It didn't work; but in the future, it will.	2024-07-06 00:05:17 +02:00
Eric-Paul Ickhorn	94a228b278	Add A20 line check This commit adds a check for whether the A20 line is usable; checking whether more than one megabyte of RAM can be used. If it isn't usable, it currently isn't activated, but rather, the boot process is stopped.	2024-07-06 00:03:48 +02:00
