start with plain water.
Member fs5500 has the same BIOS set, including sticky tape. Pictured at [here].What are those extra PROM's near the BIOS? Can we have a close up?
Edit: Ignore that. I realised you can click to zoom. Looks like the BIOS is spread across 4 chips. I've read it's an option but never seen it before!
Noting that as an option, there are at least six alternatives, per [here].One hint are the TI ZA1250 "piggyback" 128Kx1 DRAM chips. If you need to replace them, they can be a bit hard to find--but I've seen ebay sellers offering pulls.
Normal. The 5170's power-on self test does not attempt any operation on B:Also, no signs of life from the B: 5.25 floppy.
No. That card has only one connector for floppy drives. See [here].It looks like this controller card may require two floppy cables instead of one piggy backed cable.
The early BIOS that you have does not support 1.44M diskettes, but will read 720K ones. Were you using a 720K one?A: 3.5 floppy will initiate upon power up... i can hear the disk seemingly is being read but after trying multiple disks, it just loads to PC Basic... so while i hear the audio queues of the floppy working there're no visual.
Note that if you decide to swap out the 5170 motherboard's BIOS ROM's for the Award ones, in going from four 27128 ROM's to two 27256 ROM's, you will need to change the setting of shunt block U131 on the motherboard (see [here]).
Okay. See [here]. The shunt block can be taken out of its socket. Fitted to the socket in one orientation for '27128' operation, and the other orientation for '27256' operation....but, please, forgive my ignorance here. I understand that the settings need to be changed but I don't understand what i'm physically doing to change the shunt block setting. I've done switches and jumpers but never this.
every time someone uses an 8-bit IDE card on a 16-bit system an angel gets its wings clipped
What? It's an XT-IDE CF+IDE card... what's wrong with using that in this machine?
