Not new, but trial correction of IPLROM from KdL without inserting blank BIOS pages.
The maximum BIOS length is set to 512 Kbyte from address 0x780000 in EPCS64.

Hi caro. The blank pages are required to avoid some problems of functioning, however the new dual bios version that I already have ready and working will be released soon.

The Dual-BIOS is intended for EPCS16 and up (not for 1chipMSX and Zemmix Neo but for SM-X or DE boards).

DIP-SW7=OFF is EPBIOS(1) with MegaSDHC kernel + Mapper 2048 kB
DIP-SW7=ON is EPBIOS(2) with Nextor kernel + Mapper 4096 kB
The system can change the internal mapper via SETSMART command without change the current EPBIOS.
The "SDBIOS" have the priority on the EPBIOS and go in Single-BIOS mode.

I will be included with OCM-PLD v3.8 final release in the coming weeks. Wink

"v3.8 final" release Wink final comes to the version - the version is final, it doesn't mean that KdL will make no more releases Smile
