That is good knowledge kultakala, thx :) I bought a "SAFT" 14500 3,6 volt to replace the old one (same battery) and i "think" it worked once when i removed the power cord (it retained cmos values) but the second time around, i always get the cmos checksum error upon boot :( The TL-5242 is obtainable …

I'm on the hunt for a decent replacement myself a" (unfortunately i should say) i purchased a rechargeable 14500, 3.7volt battery (i say "unfortunately" because it will require a special charger as i have learned now, plus the uncertainty if it will " …

So the card arrived today and i popped it in and started the model 30/286. It immediately counted past my base ram up to 4600 (something) KB so it does recognize the additional memory. No drivers was used, it simply worked first time.

I'm still following the thread somewhat. A bit scared, atm... last week my water heater ruptured and flooded my apartment. When I came home, everyplace was a wading pool. And I had had tucked under one of my desks, still in its case, my T5200... I haven't had a chance to examine it yet, but the …

Idk if it is battery backed ( but it most probably is ). I did the Dallas hacking on my ps/2 model 30 286 last weekend and it went well, but this seems to be a different beast. It looks socketed at least so perhaps some replacement can be found if needed? The seller had it out for 90 Eur, but i made …

I have this card inbound any day now and after googling i have found drivers for the "standard" adapter (http://ibm-pc.org/drivers/memory/memory.htm) but i wonder if those drivers will also work for the "plus" version of this card? What is the difference between non-plus and plus btw?

You guys, I'm still watching this one!

Consider picking them up imho :) I bought a Cyrix CX486DRx2 20/40 and …

Little update from here: Got eprom-chips and updated both system bios and vga bios. Swapped the original 100Mb Conner to 10Gb Seagate (taken off from original XBOX long time ago). Next I'll put bigger heatsink on CPU. Got some oscillator-chips too, maybe some overclocking with 50Mhz, 60MHz, 66MHz …

Hi Vogons, i got hold of (again) my very first PC recently (last time was in 91 i think) in stellar condition (besides the Dallas RTC, but i will piggyback that with a coin-cell according to the guides available).

Hey guys, on a sidenote: when you start using the xt/at-ide instead of the native dito and it detects the HD alright and boots half way, but ends up complaining that the command can not be found, what might be the cause of this?

It is consistent. This is what it says: vram error read data 00FF00H write data 000000H It hangs on this output for some 10 seconds and then moves on to counting the RAM etc. Googling a bit (presumably?) gives me that some kind of flash i/o could be the issue and i guess it could have something to …

Update: The PSU is fine. I stripped the machine completely and opened up the PSU to see if anything seemed off, which it was not. Then i "transplanted" the working machines PSU over to this machine (and vice versa) to see if that changed anything, but it did not change anything at all (so, my …
