I've got this beautiful SD mapper/megaram card and all of the usage info I've got is by chatting with friends, isn't there any brief doc on it explaining boot keys usage and switch poistioning ?

Some info I require on SD setup :
I see that the fdisk utility can partition an SD FAT12 and FAT16, now I've made 3 partitions, two 16MB for MSXDOS1 and one larger FAT16 for MSX DOS2... How do I select a partition at boot ? Also, I see all partitions on windows disk manager, but trying to assign a drive letter to other than first goes in error. How to manage those partitions ?

Maybe mail / tweet Fabio (@fbelavenuto), and then post the info here? Smile

I think this is related to Nextor, right? The only thing on SD Mapper/Megaram (besides the hardware) that isn't Nextor is the device driver. IIRC Nextor has it's own protocol for partition management.

In that case, give the docs here a thorough read:

Hi thanks for pointing me at the nextor manual, indeed it's a Nextor info I'm missing... I think I've duly examined the document but I could not find any info on how booting from a different partition ca be done... I believe that booting is affected by the driver that initializes the boot process (hence cartridge driver) but maybe it depends on some information on the disk written to allow the booting process... I'm not much skilled on these matters... Anyone knows more ?

Create a file named NEXTOR.DAT in the partition that you want to boot from.

Oh thanks Piter ;-) Now I see that I read all the Nextor 2.0 User Manual
and this information is right into the "Nextor 2.0 Getting Started Guide" I obviously skipped to read LOL Big smile Big smile Big smile
