Hi Jarrod,

Did you use latest git tree? On Aug 8 commit
7a3a159af54d48158cb260f05043d8b503de7992 may relate to the problem.
BTW: For using interrupt 18 instead of 19,  you needed to replace, in
romprefix.S, 0x19 with 0x18 in the lines:
"pushl %es:( 0x19 * 4 )" and
"popl %es:( 0x19 * 4 )", correct?

Thanks,

Itay
