BIOS Updates forum

I've inherited an old pc chips m575, rev 1.1 based system. I found a folder on the PC Chips site by following FTP link from WIMBIOS, and a folder in the BIOS section for the 575. However, there are several rom files in there, all with the same date. I'm new to flashing, but I understood there would only be one rom file needed. Do I load one or all of these with the flash utility onto the flash floppy. There is absolutely no instruction on the PC Chips site that I can find, but there is a txt list for each file and what it seems to fix. Are these cumulative updates and I just use the highest numbered file?
Any help gratefully received

yes, all fixes included in the latest version, that's the only one you need to load.
