Test of MD40072 bios (720ME001.ROM) on M5310 Notebook My original M5310 bios is the E-bios dated 2003 07 30. This evening, I updated my M5310 bios using the bios file bioram2000.exe from the French Medion website for the Medion MF or MD 40072 "Speedmaster" notebook. The MD 40072 is apparently identical to the emachines M5310 which is actually an Arima W720K7. Bios update procedure: I downloaded and ran the bioram2000.exe file to extract the included files to a directory, the default directory is C:\Medion. The extracted files are: AUTOEXEC.BAT, 720ME001.ROM, PHLASH.EXE. and PLATFORM.BIN The autoexec.bat is specifically setup to run phlash.exe and find and install the bios file 720ME001.ROM and PLATFORM.BIN. Note that this would need to be edited to restore the original bios. Before updating the bios, I used Uniflash to save the original bios to a file naming it M5310E.ROM so that I could restore it later if necessary. I then rebooted the machine to a real DOS session (freedos dual boot) and changed to the C:\medion directory and I ran the autoexec.bat file. The new bios, platform data and bootblock were automatically installed. I rebooted the machine. A new notificaton was displayed indicating that shadowing is enabled and identifying ram usage and peripherals etc and suggesting pressing F2 to setup the CMOS. I pressed F2 and explored the CMOS setup. I noticed that the bios is identified as ME01. Flash KBC (rather than H8) was enabled for next boot. Wireless power setting was set to restore as default. Boot options were changed to Removable, Optical and HDD in that order. I do not yet know if removable will allow USB boot devices. I rebooted the machine to XP with out apparent problems or differences. I then ran an old benchmarking program WinTune 97. After several runs of wintune, the following differences became apparent: Clock speed reduced from 1879 mhz to 1851 mhz Drystone 4420mips, Whetstone 1156mflops and Video Performance 146 mp/s @ 32bpp & 1280x800, all pretty much as before. Hard-drive (cached) performance increased from 340mb/s to avg 690mb/s. Ram read decreased from 2100mb/s to 1515mb/s. I can not explain the hard drive performance increase, but the ram read decrease would probably result from adding a ram read wait state in the memory timing. If so, it should be visible in SiS Sandra benchmarking. Since installing the ME01 bios, I have run the machine for about 8 hours and I have had no problems or apparent changes to performance. www.e4all.info/motherboards/mseries_readme.txt
