So I've decide to write a new post about this problem...let's see what i can do :)
Free solutions: (Before pay)
-Cmos erase test fail (remove battery from mainboard for about 5min)
-ez flash with 1101.rom from usb and mmc test fail (if your bios has this utility)
-amiboot.rom test fail
-minidos with afudos.command test fail
-if you have other suggests add comment
Other possible solutions:
-Pc's shop (ask for repair bios; price, in italy, around 30€)
-Good bios programmer+bios chip 50€
-Chinese Bios Programmmer 10€ or less from Ebay
-Empty chip in italy 10euro; from china 2,5€
-Programmed chip 15-20€
-Soldering\desoldering about 5/10€
My final solution
Ingredients:
Friend's Heat Gun (optional); Friend's welding machine; Chinese Bios Programmer EN25T80
Time: 10min
Difficult level: Medium
1)Recognize Bios Chip on mainboard (read serial write on it) in my case MX-15G 25L8005M2C
2)With Heat Gun remove it or use welding machine (see how to do it on youtube)
3)Put Bios Chip on correspective programmer's plug (i had to push into small holes all pins)
4)Run SPI USB Flash Tool (included driver for Win 32 e 64bit) and click on Detect
6)First make a backup of your bin rom ("Read") [remember to set finish offset 8mbit=1MB]
7)Write your rom (N.B. Bios extension have to be in bin format es.1101ha.rom to 1101ha.bin)
8)Re-Read Bios and compare it with an hex editor (for ex. with Hexworkshop) to check if flashed rom is correct
9)Resolder
N.B. If bios compares are always differt check if pins are correctly inserted on plugs
If you got problems with driver download this updated package
