Commodore 386SX Bridgeboard Hacks

[superbonio]

Does anyone know where exactly, and where there is an error in the modification of the BIOS?
 Or maybe you have someone ready to program EPROM file?
 That fight with this BB A2386SX and maximally I get 8MB, after modifying the BIOS from Aminet, BB card does not start.
 Please help, can somebody spreading ready, modified the ROM file.

So, yes, I made a SIMM ZIP adapter PS2 Aminet ( http://www.heiko-pruessing.de/projects/a2386ps2/a2386ps2.html )
 I added (MA10) (Simm19pin) to the resistor R205 according to the description http://cd.textfiles.com/amigaformat/aformat-29-19980709/-Seriously_Amiga-/Emulation/A2386_16MB/A2386_16MB.guide
 Physically, I use only one base at simm (U1)
 4MB SIMM memory (8pc. Bone on one side) is seen as 4MB
 8MB SIMM memory (16pcs. SIMM bone, 8 per page) is seen as 8MB
 SIMM Memory 32MB (16pcs. SIMM bone, 8 per page) is seen as 8MB

 I did modification ROM (BIOS) of the specification http://cd.textfiles.com/amigaformat/aformat-29-19980709/-Seriously_Amiga-/Emulation/A2386_16MB/A2386_16MB.guide and programmed the new rom.
 My original ROM was like in the first post, that is, other than it should be

 From Jordan's document
 NEW OLD ADDRESS DATE DATE
 ======= ======== ========
 73a7_____b4________ff


 We A2386SX Original Binary Version 1.0
 OLD ADDRESS DATE
 ======= ========
 73a7_____e0

 Unfortunately, with the new ROM including A2386SX card does not start with any simm memory.

 Mainly I mean if someone has finished, modified, and running the file to the programmable ROM chips to recognize 16MB RAM card?
