Z80 Assembler, 50 bytes

m:db"Hello, world!\r$"
With assembler there's usually the problem which machine or operating system the program is for. I've chosen CP/M here as it runs on a variety of different machines with a Z80 processor.
CP/M programs start at address 0x100, but the decimal representation 256 is shorter.
The program loads the address of the $-terminated string into the D & E register pair, then the number of the print text subroutine (9) into the C register, and jumps to the BDOS entry. It uses the RET
urn of that routine to end itself, instead of CALL
ing the BDOS and needing an own RET
instruction in the program.
