win95 486\33SX

[JeanneD]

can you run win95 on a 486\33SX?
Min req says 386DX, so I wasn't sure if that meant you have to have math coprocessor or not......

[bdunn]

Yes you can run windows 95 on a 486sx. But at that speed 33MHz it will be awful slow.

Despite what microsoft says infact you can even run it on a 386sx with a lot of configuration and trickery. I had to do this once for someone refusing to retire his laptop. I wouldn't recommend this though.

there is no problem at all,but you need at least 16megs of ramif you want to see it move at all,Clauded

hi
I thought it should..the guy had installed win95 upgrade over win3.1 and it worked but I put 64mb ram in it and a modem and the registry blew...I ended up fdisk & reformatting about 5 times and after each successful install, eventually the same thing.."windows detected a registry problem...restart to reinitialize" or something like that...eventually after couple restarts I have nothing in devices left.
Its a IBM PS\1 w\ SB16 (old one, prop CDRom)
trident 8900c (Which I put in see if it would help-has OB 512k cirrus logic) 2- 240mb HD,
and now Jaton modem. I now installed win95B to see if it fixes problem and seems good but did get that error once since, seemed fine after restart but made me nervous. Told the guy for the $200 he spent on ram and modem for this junk I could almost have built cheap
cyrix or amd new system...but he insisted, I now have about 10 hours into it (and I charged him only flat $25) and I am still worried about it going bad, never want to see it again =( Any ideas be appreciated

I would be suspicious of the RAM. Did you ever test his RAM in another sysem, or try some different RAM in his?

[JeanneD]

actually i was suspicious but I tested it on a simm tester and it seems fine, unless its just not showing

UPDATE: I actually gave up and gave the guy a diff case w\ a P100 and all diff parts except
the ram...worked fine couple days, then guess what? same error shows up again. Simm tester showed they were fine (and I ran thorough test with heat cycling and stuff) but they must have some kind of problem obviously....took it out put in some I had and so far, so good.
Thanx again for the responses... =)

Jeanne... For what it may be worth, and it may be nothing, but are you aware that the older 486 and the Tx Pentium mainboards can't cache that amount of ram.

[JeanneD]

just to answer, that pc had a manual and a label on it saying 4-64mb ram capable, and the P100 I tried it in had a brand new tx-proII board capable of like 6x that much ram.... anyhow, pc is running great since I dumped that ram, maybe they sold me some type of proprietary ram when I told them it was a 486\33, sent it back for exchange for edo to use somewhere else....

I was runing a 486dx2/66 with 12mb ram 500mb hd and a 14.4 modem win95 did great infact it does better than my cyrix200 computer only dont install duil os like linux and win95 it mess up fat16. I even know some one that put win95 on a 8088 ehehe ran bad tho.

I had the same Problem (a Message like damaged Registry) after installing new RAM (in a 266MMX). The new RAM was a 100MHz SDRAM, but my board only works with 66MHz RAM! I think your Problem is even the RAM.
You should use Fast Page Mode RAM, not EDO.

[JeanneD]

thanx for the replies... the 64mb I put in first was FP, not EDO...
altho some of the newer 486 pci boards can use EDO, this wasn't one of them.....

I have had good luck with 95 on even 486\33 DX or 66 DX2, ran it for a while even on a 386\40DX for the heck of it (worked but slow of course) but had never tried on an SX before...
have a great day, see ya...

maximum memory i would recommend for that setup is 12 or 16 meg

also as a memo you can install win 98 in a system with a 50mhz processor and 12 meg of ram
it runs slow but it will work

[AlienDyne]

I had a 386dx-40 with 8Megs of ram and no coprocessor installed, before 4years. I had installed win95 without any big problems.
It needed about 5mins to start windows, but it worked fine (and slow too). In my opinion, the coprocessor is needed for a better performance but it is not a major problem if not present. Give it a try.
Good luck...

HI Jeanne I have am IBM ps-1 value point siting here doing nothing , I was buliding it up for my Dad and when I bought some non parity ram 16 megs ans popped it in the mother board did not even recognize it ( 16 meg simm ) I was all over the IBM site and I saw that the board could handle that simm but not this unit , it would only reccognize the originla 8 meg simm it came with and it ran at 85 nano seconds where the newer simm was faster, I even tried the new simm alone and the computer would not boot
I think these ps-1 machines have a memory problem
I would up stripping it down for parts and building a system from scratch and it runs better than my Pentium and it runs Win 98 nicely

COOL !
Once I needed to upgrade IBM PS1 from 386SX-25MHz to 486-40MHz (not Intel and not DX) to run Win95. This system had 10MB RAM 30pin (4-4, 1-1). It works.
