![]() However it is not too hard to rewrite everything on an Atari ST, including the BIOS. You can not remove all ROM chips but neither can you do so on a PC. You can actually remove 4 from the 6 ROM chips and the Atari can still execute the boot sector. When TOS tests for an executable bootsector only the BIOS is active, just like on a PC. Also most demos completely bypass all ROM OS routines after the boot sector is executed. The modern ST's have the complete OS in ROM but you can still boot a new OS from a floppy, like MiNT of Magic or Linux on Falcon or TT. The first ST had also only BIOS in ROM, the rest of the OS was loaded from floppy. This can be MS DOS 3.30, windows 95, Windows XP, Linux, Free BSD etc. Like if somebody stole your TOS chipsĪ normal PC comes with the BIOS in ROM. Yes, I thought it myself, but this means that the TOS is still loaded, right? I mean, my friend was "challenging" with the idea of using the machine with a complete different OS. Use TOS as a simple BIOS to load the first bootsector and user whatever code from that to boot a custom kernel to takeover the machine.
