The above code takes the logical disk geometry as detected or configured in the BIOS and multiplies the coordinates together to obtain a count of sectors times 4. That value is then divided by 7812 (almost exactly the number of sectors in one SI megabyte) to obtain the number of megabytes. The division instruction at E000:8B15 takes the dividend from the 32-bit register pair DX:AX (where the multiplication instruction put it) and returns the quotient in the 16-bit register AX. If the quotient happens not to fit within 16 bits, the divide instruction triggers a #DE (divide error) exception, more commonly known for being triggered when attempting to divide by zero. Since the BIOS had not installed a meaningful divide error handler by that moment, the boot process hangs.
Finally, if you've got a suitable Windows (eg. one of the Windows XP testing images that used to be offered on modern.ie before Microsoft EOLed earlier versions of Internet Explorer), you could mount a floppy drive or disk image as A: in a PC emulator/virtual machine manager and create an install disk that way... assuming that Wine doesn't offer a translation of the relevant APIs and none of the relevant disk image generators are DOS EXEs that'll work in something like DOSBox-X.
