Thanks for the information :) that mod seems doable, but a bit too involved for me atm.. This is my only working 486 board and I'm going to play it safe. I do want to do some tests on it, to compare the performance and see if it remains stable under stress. What programs can I use? Does this …

So this DMI data is needed even before the BIOS can attempt to start a failsafe recovery? What is your source on this being a known issue with your board? Information from this link: http://www.motherboards.org/forums/viewtopic.php?t=76346 seems to indicate that the DMI data comes from the system …

A modern BIOS like that certainly has a 'Boot block' protection. It should be possible to fix it without replacing the chip or using an external programmer. Look here for example: http://www.biosflash.com/e/bios-update-error.htm, or try searching google for 'bootblock aspire t180' or such.

Hi, I tried three different cards, in the three different pci slots. They give either a blank screen or a garbled screen after POST. I don't know the impact of the setting, and I don't have another working board to test it. It's possible that the cap wasn't there in the first place, but I doubt it: …

I'd be somewhat interested in this myself actually. I did once come across some youtube vid which was basically a music video showing how to reflow some PCI-E graphics card or something lol! I'm pretty sure some of these should exist, perhaps search for something about the recapping of motherboard? …

Seems like it worked! I created a floppy with a tool called WINCRISIS, using the latest BIOS from fujitsu (H2U_A1F.ABL in my case). The filename had to be renamed to BIOS.WPH for the tool. Then, with the switch set to BB enable, I inserted the floppy and turned on the laptop. It started reading the …

I don't know. If your BIOS chip is socketed (I really don't know how this is done for laptops, but I reckon most weren't socketed due to space constraints), I'd say the easiest way is to reflash it somehow, I've heard good things about EPROM burners but never used one myself. Yes, I was initially …

Hi, The roland card is currently removed. When I let the BIOS automatically assign IRQs (or when I set PnP OS to yes in the BIOS) the soundblaster gets IRQ5, DMA1 & 3 and IO 220, 330 & 388 in the device manager (default setting from windows, not user defined). Device manager shows no conflicts and …

Removing the Roland card didn't help and I confirmed that when the soundblaster uses IRQ5 windows uses a configuration with I/O address 330 instead of 300. That explains the wrong sounding music, but sound effects still aren't working.
