NEC usb hack for mediator

[slaapliedje]

Oops!  Well, count me in for one!  I have had a few crappy months and couldn't get any money to put toward my Amiga.

I have also wanted to clear up the lock ups that I posted in a different thread.

If you do, let us know. I never got it to work in my A1200T but it works a treat in my A4000D. So much so, I figured I'd buy another one.

Just to let you lot know: I tested one of these NEC usb cards and it works great even with the latest spider.device 3.22. No RDB trashing seems to be going on...

Seems like I have one of these compatible NEC USB cards. It shows up in pciinfo at least. Is there any other way to flash the card other than desoldering the chip?

I notice it was a while since last activity on this thread.

I can report that new cards with the suitable chip, D720101F1, are flourishing on eBay for just a few USD including shipping.
I also noticed a new card being sold with no eprom, wonder where it would keep the ID..

As for the programming of the chip, what kit did you use? I suppose it is as easy as reading the contents, searching current device ID with an hex-editor, and replace it with the "Elbox Device ID", then write back?
(Would be neat writing a piece of software that would update the flash, if physically reachable through the PCI-bus).

Has the opposite been tried, searching through pci.library / spider.device, replacing the elbox ID with that of the card (NEC ID..?). If success, no modification to the card would be needed..

Thanks!

I used a BPmicrosystems BP-1600 eprom burner with soic adapter. Read out the serial eprom, edit it, and shoot it back. if course it means desoldering the chip to do this.  yes i guess the driver itself could be hacked,assuming that is the only thing that looks for the ID.
There is prob. a way to jtag it while on the board,but i dont know of one.

Would you reprogram eprom from my card? I will desolder it... and put it back?

[amiadudeorwat]

NEC/Renesas apparently had a utility to program the ROM on board, though I was unable to track it down.  The few people that still have it are unwilling to share.

Im interested in one. Depending on price and how idiot proof it is for myself
