Hello!
AmiBIOS (C) 1994 has very limited LBA support.
Function 0x42 (LBA read) is not supported.
The question "should use CHS instead?" has an answer "Yes".
It is certainly better that just print "Read Error" and stop.
The situation is different in start.S
If the Stage 1 indicates that LBA was used, then errors in start.S are
actually read errors.
ChangeLog:
* stage1/stage1.S: fallback to CHS if LBA read is not supported
PS. I think I'm now eligible for Boston Hurd User Group :-)
Feel free to contact me in private.
