OK sorry. This has been explained to me properly on IRC now:
13:57 If you are using a USB keyboard, then you can work around the
broken UEFI firmware by using iPXE's own USB keyboard driver
13:57 (instead of the UEFI keyboard driver)
13:58 You can trivially verify the the problem is independent of iPXE by
e.g. booting straight into the UEFI shell
13:58 You will find that, for example, "Ctrl-C" acts as just "C"
Which is great. It would be even better to know / have documented
somewhere (relevant places) how users can do that!
You could also try this patch:
diff --git a/src/core/getkey.c b/src/core/getkey.c
index 0f0f8b7..0c280d2 100644
--- a/src/core/getkey.c
+++ b/src/core/getkey.c
@@ -76,9 +76,14 @@ int getkey ( unsigned long timeout ) {
if ( character != ESC )
return character;
+ character = getchar_timeout ( GETKEY_TIMEOUT );
+ if ( character < 0 )
+ return ESC;
+
+ if ( isalpha ( character ) )
+ return ( toupper ( character ) - 'A' + 1 );
+
while ( ( character = getchar_timeout ( GETKEY_TIMEOUT ) ) >= 0 ) {
- if ( character == '[' )
- continue;
if ( isdigit ( character ) ) {
n = ( ( n * 10 ) + ( character - '0' ) );
continue;
which should allow you to emulate Ctrl-<key> by pressing ESC,<key> (with
less than 0.25s between ESC and the other key).
