WEBAccidentally using a decimal value in an INT opcode is a very common source of errors when using BIOS functions. To an extent, the BIOS functions are organized by interrupt number: INT 0x10 = Video display functions (including VESA/VBE) INT 0x13 = mass storage (disk, floppy) access. INT 0x15 = memory size functions.

WEBOct 3, 2015 · int 10 contains no letters so it is decimal 10 (or hexadecimal a ). 0eh ends with a letter and doesn't start with 0 and a letter so h is the suffix. h means hexadecimal. So 0eh is hexadecimal 0e (or decimal 14 ). If you were to put that into assembler code for the BIOS it would look like (using hexadecimal suffix):
