Porting woes: INITENV was originally paragraph-aligned already

[ecm-pushbx]

The main change in a9adbbf just undoes what f4e868e#diff-52bbf87db189a4af9f24037eb12b3b9563a54bfc343b81073ad25c86fbf9f5dcL111 did!

[boeckmann]

Yes, wondering why it was not implicitly para-aligned by the previous definition in BIOSGRPS. There it is para-aligned. And this should have propagated to the INITENV in the genercfg.asm.

[boeckmann]

Btw @ecm-pushbx do you think we can safely remove the 256 byte patch area filled by NOP? To my understanding, we can simply rebuild the kernel if there is something to patch?

[ecm-pushbx]

I assume you mean

edrdos/drbio/biosinit.asm

Line 292 in 83b6630

;

and

edrdos/drdos/header.asm

Line 1392 in 83b6630

patch_area dw 0666h

?

I don't know what exactly this was intended for. You're of the opinion it is for hot patching existing kernel files, to ease this sort of patch? If that is indeed the only use then yeah I'd say drop it.

[boeckmann]

Exactly, found no other reference to it in the source, so I assume this is for hot patching. But I am not 100% sure. Who knows what legacy DOS program could depend on this?

[ecm-pushbx]

It is no more than 512 Bytes, maybe less (not sure whether the bio patch is init only area or resident). So I'd rather be careful for now.
