The parser only accepts a single-digit entry for both drive number and partition number. If you attempt to enter,= for example, 0:da(0p21) it doesn't accept it; the default changes to 0:da(0p2) = when the prompt is re-displayed. The code that parses the string also tries to allow the drive number to be = left off and the unit number becomes the drive number (i.e., da(5p11) would be equivelent to 5:da(0p11)), except that the code doesn't zero out the unit number after transposing it to the drive number, so you really get 5:da(5p1= 1) which is unlikely to ever be right (this is just something I noticed while looking at parse_cmds() in gptboot.c). I originally intended to just fix the parsing code, but then I discovered t= hat its current behavior is undocumented (there is no mention of handling gpt partitions using a 'pNN' syntax at all, as well as no mention of reinterpre= ting unit number as drive number). That means any change to this code at all mi= ght break somebody's existing configuration, and I'm just not going to open that can of worms today. --=20 You are receiving this mail because: You are the assignee for the bug.=
