From 7292e4a0a8f58333ccbd2d0d47242f9865083c9c Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 16 Apr 2021 08:57:02 +0200 Subject: Increase BUILD_MIN_BIOSTABLE for large roms BUILD_MIN_BIOSTABLE reserves space in the f-segment. Some data structures -- for example disk drives known to seabios -- must be stored there, so the space available here limits the number of devices seabios is able to manage. This patch sets BUILD_MIN_BIOSTABLE to 8k for bios images being 256k or larger in size. 32bit code is moved off in that case, so we have more room in the f-segment then.
