Subject: If the file (created by setup) exists, use boot parameters from there
X-Git-Tag: v3.1.0~841
X-Git-Url: http://zhaoyanbai.com/repos/Bv9ARM.ch13.html?a=commitdiff_plain;h=e248f7c1a3e5334cf9986e409f4a3e29fe69882f;p=minix.git

If the file (created by setup) exists, use boot parameters from there
for the boot floppy instead of copying it from the current root partition.
This makes making a boot floppy at installation time before booting from
the new system possible (conveniently).
