It's running Bios 5.4.03 ( I have the screen to setup the raid on boot ) and both DOS and Windows are working fine without using the "Base" Bios. Just the speed that seems to be very low.
Do you think that flashing the Bios to the Base one will improve the speed under w98 ?
So, the BIOS version doesn't directly affect the speed in Windows 98. What does improve the speed is having the correct 32bit drivers installed - the drivers will take over from the BIOS and enable DMA, and everything should then get fast.
But the problem is that in order for the driver to load correctly in Windows, the driver version has to support the BIOS version on the card. And there are (as far as I can tell) no Windows 98 drivers which support the 5.4.03 RAID BIOS. (On Win2k/XP and later you can use the 3114R5 1.5.10.0 or later drivers with this BIOS.)
So, to improve your speed you have two options:
- Install the Base bios version 5.4.03 (b5403.bin) on the card. Then you can install the Windows 98 non-raid driver version 1.3.10.0 (3114-vista-x86-logo-1.3.10.0.zip)
- Install the RAID bios version 5.0.73 (r5073.bin) on the card. Then you can install the Windows 98 raid driver version 1.0.20.0 (3114_x86_10200_logo.zip)
I personally use the latter option - I found that the bios version 5.0.73 was more compatible with my Socket 7 motherboard's bios. Your mileage may vary - if one option doesn't work, try the other.
The mentioned driver and bios versions are all in the 3114 driver archive file on https://www.philscomputerlab.com/silicon-image-sil311x.html
