Avoiding UEFI for the ROS sake?

Sanity's sake. UEFI is a dumpster fire.

The only two good features are GPT, which doesn't require UEFI anyway, and Secure Boot, which is generally unnecessary on a personal system.

GPT not requiring UEFI instead requires an BIOS GRUB partition, in order to function on legacy boot

How to install and boot ROS on an GPT SSD w/o UEFI, but with multiboot alongside UEFI booted FreeBSD and Linux?

I give no shits about apple

GRUB is not the only bootloader that knows how to deal with GPT, but the basic idea is that: BIOS booting works by jumping program execution to a disk. The code on the first sector of the disk should know enough to read whatever data it needs (and often that's via MBR or GPT partitions)

ReactOS doesn't have GPT support. You'd be better off sticking with MBR. if you really want to, try a hybrid MBR/GPT. The UEFI multiboot stuff isn't really something I care about at all. I can't even get the damn thing to work with a single OS.

hypothetically I guess you're supposed to put PE files on a ESP and then use efivarmgr to configure what to boot

Hybrid GPT/MBR? The rEFInd author Roderick W Smith doesn't recommend at all in his books

There is a reason I said "if you really want to"

https://www.rodsbooks.com/gdisk/hybrid.html

all this talk is mostly academic anyway. I run Linux. I have four hard disks in a 100% redundant configuration, I want to have the ability to lose an arbitrary hard disk and my booting to be unaffected. Impossible with UEFI, trivially simple with BIOS.

Linux and ROS multiboot with just legacy BIOS?

Probably easy.

And how easy is it also to multiboot UEFI emulations (on actually legacy BIOS) and ROS?

what's with all the questions?

Fake UEFI on actually legacy BIOS And alongside ROS

ReactOS doesn't have UEFI support.

also it seems that the existence of GPT is enough to make ReactOS BSOD :D

But unfortunately w/o affecting UEFI OS'es at all

This doesn't have anything to do with UEFI

seriously dude

GPT getting ROS BSOD?

That is what I said

also it's probably unrelated after all. Any FAT is now broken. WTF :D

plain old MBR

LiveCD issue apparently. regular install works fine, and I was wrong about lack of GPT support. It does have it.

ROS doesn't lack GPT supports, but how does GPT still gets ROS BSoD?

Instead of asking others to do your research, just try it out yourself

ROS doesn't lack GPT supports, but how does GPT still gets ROS BSoD?

As far as I know, support for GPT in setup is unimplemented.

You can access GPT disks with LiveCD.

Our new storage stack supports it.

👍🏻👍🏻

I’ve also done my own research at about 2019, but wasn’t going to understand at all

Even with my nice FreeBSD and Linux experiences, but still no ideas to ROS, due to Windows-like instead of UNIX-like

Are ROS terminal commands the similar to the Windows / FreeDOS ones?

You can access GPT disks with LiveCD.

I’ve also tested the LiveCD using UEFI boot, but it says no UEFI loaders for AMD64-EFI, so unable to further test ROS by my only laptop

Similar to CMD.exe, yes.

UEFI support is unfinished

It is not usable

Thanks

nooooo of course not why would they be the same

hbelusca (Gmunu=8PiG/c4Tmunu)#6742: you're trolling Eris Lund ?

more frustrated that people for some reason ask questions that shouldnt need asking if they have done at least a bit of research

hbelusca (Gmunu=8PiG/c4Tmunu)#6742: ok 😄

That new systems like Asus Ryzen 9 3900 ones, but still have legacy BIOS available? And i'm going to install ROS on an GPT SSD With rEFInd to boot FreeBSD, Linux, and Illumos And with BIOS GRUB partition to boot ROS A good idea?

why are you so surprised?

Not being neccessarily surprised And FreeDOS is being gone from being installed on new systems Their devels told me they would use vintage systems (as seen to us) forever

Won't the real hardware world be soon passing legacy BIOS away?

It's likely a bad news for our incompletion for UEFI

You have one strange fixation on this detail.

It's pretty minor in reality. Basically everything has a legacy boot option, and especially VMs.

Legacy BIOS on the virts will never be dead yes But on real hardware it's completely an uncertainty

At a day real hardware world might end legacy BIOS at all Though impossible for virts to end legacy BIOS

that day is not any time soon

like I already said, I'd hope it never comes. BIOS booting is simple, easy to understand, works in scenarios UEFI would prefer don't exist.

that day is not any time soon

Yes unlikely soon to us But if your son were getting old (if any) it will be soon to his generation to see the end of legacy BIOS

mandatory FAT partition is just..... why? who thought that could ever be a good idea?

mandatory FAT partition is just..... why? who thought that could ever be a good idea?

Honestly yes UEFI requires files to function Legacy BIOS on GPT schemes expects just an BIOS GRUB partition But no files are required at all, unlike UEFI

I already explained how that's false :P

BIOS doesn't care about GRUB. It shouldn't even care about MBR or GPT. It just jumps program execution.

There are exceptions on the last point, almost always related to virus detection features some of them have.

👍🏻👍🏻

Thanks

BIOS does have rough edges, mostly the ignored real-mode components that actually make it a input/output system. It was originally designed to offshore operating system functions so the DOS kernel could be minimally small on the small (160KB) floppy discs of 1981. That's basically always ignored unless you boot MS-DOS on your computer for some reason.

Well, it is working without exploding! Good news
