We recently have upgraded syslinux and have noticed that the boot logo code via boot.txt no longer works. I have a couple patches that get it close to working but I appear to be having trouble with color maps. Is there someone would want to help me finish figuring this out? Any interest in the patches I have to fix the rle decoder?

...ve no dma errors. I had to adjust 2 rejects of 0.0.7a by hand (posted about these on the list), so you can say the problem is me and not ext3 :-). See at the end of this email.

The % is modulus (remainder) operator and ^ is bitwise. In this context, we take a file, and go through each character and encrypt it. But why are the ^ and % operators used here: def encrypt(reader, writer) key_index = 0 while not reader.eof? clear_char = reader.getc encrypted_char = clear_char ^ @key[key_index] writer.putc(encrypted_char) key_index = (key_index + 1) % @key.size end end thanks for response -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi, the display of LSS16 files from a DISPLAY file (as documented in http://www.syslinux.org/wiki/index.php/SYSLINUX#Display_graphic_from_filename:) seems heavily broken since syslinux has been converted from assembler to C. I already discovered one bug in core/include/graphics.h (and core/graphics.c): the pointer VGAFilePtr is of type uint16_t*, but should be plain char*. This bug causes the
