Yesterday I woke another old-PC from hibernation that I had kept aside for several years, it is a Pentium 60 SKT4, the motherboard is AT with Intel 8243X LX chipset.
This card is from Intel, in this case the card model is Hendrix (or so it seems they call it), it has the VGA on board with 1MB of RAM expandable to 2MB, the VGA chip is from Cirrus Logic GD5434, but for to make it work you need an AT power supply with P10 connector (in addition to P8 and P9) and a special card for connecting the VGA port to the MB (which I do not have), if you want the problem of the card can be overcome, making one by hand with a little of recycled materials (scrap motherboards), for PIN connections should not be complicated, just look at the connections of a VGA to understand what individual PINs are. For the moment I remedied by installing a VGA PCI (if desired, an ISA would also be fine), to be precise a SIS 6215 with 2MB of RAM, I tried other cards including a matrox mystique and G450 but it did not display anything in the monitor the same with the ATI Rage XL, maybe the problem could be the monitor, at the moment I have two that are broken and I should fix, one I remember having problems with the Vga Matrox not displaying anything, so maybe this is the cause, maybe there is some difference video signal, and some older monitors don't detect it.
Returning to the MB it starts correctly displaying the BIOS screen, from here I detect the AMI BIOS version 1.00.02.BL0, the installed RAM is only 48MB while the RAMs are all 16MB each (so they would be 64MB), trying and trying again the two pairs, I notice that a pair of 16MB is read for half, then I replace it with a pair of 8MB each, now the 48MB are detected correctly, I notice in one of the RAM slots a Pin between 72 that is folded and almost goes to touch the neighboring one, unfortunately I was unable to straighten it because it broke, but despite this the RAMs are read correctly, perhaps it is a mass or common PIN so the absence is not noticed.
Unfortunately it has a dallas DS12887 RTC chip with low battery, to which you have to do the MOD., It is not so much for the low battery, but for the BIOS info that is lost at every boot, also there is a bug to the bios, at least for the moment you do not enter by pressing F1, pressing it the PC freezes. The only thing possible is to boot it from floppy. But even here for the moment it doesn't work, maybe it's the reader or the floppies that are missing, I should try other ones that are sure to work and see what happens (that is, if it starts).
