Re: turboR DRAM mode & DOS2
Hello, >When using As long as I have a Turbo-R I use a small programm called CHGCPU.COM... very easy at use, simply typing on the commandline of MSX-DOS what you want the programm to do... I'm sure this programm can be found somewhere on Funet, if not, let me know then I willupload it or send it to you! --[ MARI ]-- -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html

Re: turboR DRAM mode & DOS2
There are some utils to change the Turbo R state from DRAM to ROM and back. They are called romturbo.com and ramturbo.com. I can mail them to you, just let me know. Or try it to upload to funet...

I have tried switching to R800 ROM >or Z80 mode and rebooting DOS2 (BASIC then CALL SYSTEM), but that does not >work. 1. The DOS2 system segment reside in the highest parts of the primary mapper. Since the highest 4 banks are reserved for the 64 kB for R800 DRAM mode. Two segments are taken by DOS2 for the system and (when using COMMAND2.COM version 2.4 or higher) another two segments are taken for alias/history and .BTM file use. 2. When you switch to R800 ROM they will be free to use, though not to DOS2. DOS2 will always boot into R800 DRAM mode, so switching to Basic and CALL SYSTEM after Z80 or R800 ROM setting is quite useless. The other reply stating pressing 2 while booting turbo R will not work either. There are two methods to set DOS mode at boot-up: 1. A disk with a DOS2 boot-sector (contains "VOL_ID" from offset &H20) will boot into DOS2 and without a disk will boot in to DOS2 as well 2. A diisk which doesn't have a DOS2 boot-sector (missing "VOL_ID") will boot into DOS1. Pressing 1 at boot-up will force the system to boot into DOS1 no matter what the boot-sector of the disk states.

turboR DRAM mode & DOS2
Hi all, me again with another DOS2 problem. On turboR an extra 64kB memory is used by the system. I guess this is the DRAM mode memory. Now I have these questions: 1. Do the DOS2 system segments reside before or after the DRAM memory? 2. Is there any way to free this 64kB? I have tried switching to R800 ROM or Z80 mode and rebooting DOS2 (BASIC then CALL SYSTEM), but that does not work. Thanks, Patriek -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html
