Modded BIOS for the JMB363. Exposes the ports as a standard IDE as well as AHCI-compliant SATA controller respectively. No third-party drivers necessary.
Don't forget to back up the original BIOS first in case something goes wrong!

It's probably easiest to create a bootable FreeDOS environment on an USB stick by using Rufus.

-----------------------

Syntax (Under DOS environment):


36xupd [/w [s]] [/r [s]] [/e [s]] [/s [w | r | e]] file_name filename Specifies a file which include new BIOS or a target file to back up the the file


/w [s] Update Option ROM [use SPI]
/r [s] Backup Option ROM [use SPI]
/e [s] Erase Whole Flash [use SPI] (without file_name)
/s w Update SPI256
/s r Backup SPI256
/s e Erase SPI256 (without file_name)

 

[Notice]


For 37X and 363C, the program would auto-load "SPI256.bin" as the
first 256 Bytes of SPI Flash for SPI Initial Load feature.
If SPI256.bin does not exist, the first 256 bytes would be filled with 0xFF.
