Stack Size Required to Abort BIOS Call

I am working on a small bootloader for training. Is there any specification / information about the size of the (free) stack that is required to cause a BIOS interrupt?

Before entering the interrupt handler, all the registers are pushed onto the stack together with the address with distant feedback, they sum the sizes of the registers and add the space needed to store the return address in order to get the minimum stack size.

note that you need more space if you push more data on the stack and in the interrupt handler

The happy answer is that BIOS interrupts (with the exception of the new bloated PCI) are designed to run in minimal space, so there is no need to install the stack in the boot sector.
