BIOS Updates forum

Looking for a bios image for this laptop to fix a bad flash that rendered it
useless some time ago. AMS Tech is dead and gone.

Orpah laptops has only this to say about the 185:

Im using dos debug. I wasnt showing the byte swapped opcode, just the program listing. Anyway mov ax,0007 is indeed correct for setting mda mode. ah=0 al=7. Trace a simple program like the following and the registers match. Sorry if this causes confusion. B80700 MOV AX,0007 B700 MOV BH,00 B307 MOV B...

CALL FAR C000:0003 MOV AX,0007 INT 10 (now the default card is set to mda mode) CALL FAR xxxx:0003 MOV AX,0003 INT 10 (pci card/bios is alive in ega) ... Those last 3 lines are just for experimentation outside the bios, ie in dos. I suppose nothing really prevents their inclusion. If so, however, th...

One trick might be to asap put the onboard vga card into MDA mode, then initialize the PCI/etc card. If the onboard card does a good job of strictly emulating MDA, coexistence with another vga card should be no problem (port and memory IO wise). If you can pre-initialize the onboard card into MDA mo...

PCI board but no flash.
AT27C010 is an EPROM.

Time to start digging.

Could be any one of : http://drivers.infomaniak.ch/main.php?sDirectory=Drivers/Fic/Utilitaire/ Looks like flash52c is the one of the earliest versions around (if not the earliest). If your board is one of the later models (ie with PCI slots or VLB that supports bus mastering), you might be in luck. ...

:P woohoo :P After some bugfixing to the driver, it now works as expected. The energy* logo now appears as well. The problems I had were due to the driver forcing mode 03 and clearing the screen on initialization. Also, mode's 8x were not properly trapped and caused the cmos config screen to jump in...

8O how simple. Acutally, it does clear up some things. It looks like nothing really prevents writing to local data segments so long as the memory is not explicitly locked. But then what is the techique to locking memory (making it read-only)? Is this a chipset-specific thing? Are there well known fl...

Sorry, when I said "EPA Procedure", I was moreless referring to the code that draws the EPA logo on the screen. I may very well have made a modification to the EPA procedure itself (ie a method within). For me, however, this is desirable. Since I want the video bios to initialize and insert its int1...

I was successful in patching my Award 4.51pg bios to post in an NTSC video mode. Many old mono monitors, TV's, small LCD's etc are fixed-scan at NTSC clockrates and have different sync-pulse characteristics. Most, if not all, VGA cards can drive at these rates, but there was never an "official IBM" ...
