plat/msdos386: refactor, firm up, and optimize - refactor code for transfer buffer reads/writes, real mode int 0x21 calls, and assembler segment declarations - define transfer buffer size in one place - beef up error checking for transfer buffer operations (prevent buffer overflows) - also optimize such operations to transfer dword by dword where feasible 2022-08-26 17:20:56 +00:00			`#`

Programs now start up and can write to the console, but crash when reading. 2022-08-17 22:24:08 +00:00

Most of read and write now works; filename-based operations partially work; but there's a nasty memory corruption somewhere which needs investigating. 2022-08-18 22:08:57 +00:00			`mov ebx, esp`
