Technically, the answer is:

movb %es:0x1a,%ch

But! GAS has been known to have bugs with segment overrides. The following
would probably be safer:

byte 0x26 # seg es
movb 0x1a,%ch

Another point: That instruction is *very* unlikely to do anything useful in
protected mode.  Unless you have changed `es', it will SIGSEGV.  Reconsider
what it's supposed to do.
