flashrom recognizes the chip as winbond W39V040B, which corresponds with what I can make out of the lettering on the chip.
This is a 4Mbit 3.3V LPC flash chip.
You could go all the way up to 16Mbit with a SST49LF160C-33-4C-NHE, or for 8Mbit try SST49LF080A-33-4C-NHE.
Another 8Mbit option is Winbond W39V080APZ.
I found no offers for these in .ie.
http://bios-repair.co.uk/bios/eeprom.htm have 16Mbit SST, 8Mbit SST and 8Mbit Winbond. I would buy SST. We've seen some Winbond chips fail mysteriously. :\
