x1950 pro bad flash

[TI66ER]

I have a sapphire pci-e 1950 pro 512mb,which i had flashed with the clocks oc'd a bit because i could clock it on vista.Last night i tried flashing it with atiwinflash which i have used numerous times with no probs.As soon as i pressed program to flash it,it froze and i had to reset.Well you guessed it,no video and no post with the card in it.I have put the card in using a 1mb pci card for display,and tried using atiflash and flash rom in dos as follows-

atiflash -i result-no ati card detected
flashrom -i result-no ati card detected.

I am using a 1mb pci card till i can sort this or rma it.

would this work?-

my rom chip is a st M25P10VP,the guys in the thread and w1zzards chip were M25P05V6.

I hope it is possible to recover this card,as i have nothing else to use while its away for an rma.

thanks guys.
