That's my point, because that's what the MSX2 Technical Handbook says: ---------------------------------------------------------------------------- In some cases, however, it is required to know the slot number of the specified software. For example, in the previous version, BASIC MAIN-ROM was placed in basic slot #0 or in expansion slot #0-0 when basic slot #0 was expanded. So when MSX1 is upgraded to have the MSX2 functions by installing MSX-VIDEO and BASIC ver 2.0 ROM, the MAIN ROM should be placed somewhere other than slot #0 or slot #0-0. The slot where MSX2 SUB-ROM resides depends on the machine, but the information about the slot where BASIC interpreter ROM resides can be obtained by referring to the work area described below ---------------------------------------------------------------------------- > The slot containing the BIOS which should be used on a MSX computer > can be found at location #FCC1.

But #FCC1 is RAM. The slot address in that system variable is set by the BIOS at boot time. Now let's say that the BIOS didn't to that job for me. How could I find out where's the MAIN-ROM for that computer? Regards, -- Javi Lavandeira ([EMAIL PROTECTED]) - http://www.ag0ny.com -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html
