IBM is one of the better Manufactures out there to find documentation on their systems. You can garrentee there is a service manual available for anything of their's produced in the 1990s.

The IBM PC300 series was predominantly used in bussiness/enterprise space. 486s were still the predominent class of system in use when Windows 95 was released..

you haven't reply at my post, the graphic and ide chip on the mainboard, are connected to the system in ISA or VLBUS??

The 486 IBM PS/1 came preloaded with DOS and Win3.1 ( 16-bit operating systems ).
Windows 95 was a 32-bit operating system. It was a different era in computing and hardware.

Some of the fastest video cards available for the VLB slot where the Cirrus Logic 5426, 5428 and 5429.
The 5430 was only available on PCI and was onboard on the 486 IBM 330 computer.

we talk about the ps/1 not the 330. Again, wich type of bus have the integrated gpu and controller in the ps/1? tnks

99% it's internal VLB , they would not use a 5430 with an isa interface when integrating to a motherboard

486s ARE 32-bit systems. Windows 95 was designed to WORK on 486s (it was the predominantly used cpu type at the time of release) and REPLACE Dos/win3.x. It was BACKWARD compatible and totally suitable for those systems if they fitted the hardware requirements and very capable running most Dos and win3.x programs. Hence the release of Windows 95 UPGRADE at the product launch. In case you didn't know 486s are quite capable of running 32 bit software/operating systems such as NT 3.x, Linux, OS/2 v2-3(an IBM product and available for your system if the customer wanted it at purchase) and a few others. My Compaq Presario CDS524 ran Mandrake 6.1 just fine wich is a 32-bit OS released 6 years after the system was sold. See all the software to the left in the image below.

Just because a system was bundled with certain software/operating system doesn't mean it is incapable of running other software/operating systems. An example my Compaq all-in-one P75 system is a 32-bit system but it was shipped with MSDos6.22/Windows 3.11. When windows 95 came out those still up for sale and even those already bought were offered Windows 95 (usually via a Windows 95 promo card on purchase) or had Windows 95 UPGRADE bundled with the original dos/win3.x package when sold after Windows 95s release. I have ALL the original software for that system to prove it.

Lol.
Yeah, i remember the launch of Win95. I went to Great America amusement park just to get a FREE copy of the eval.
But it was to much for my 486dx33 with VLB motherboard and only 8mb of ram.
So I had to upgrade my computer.
The IBM PS/1 came with 486sx, 4mb of ram and onboard Cirrus Logic 5428.
This was okay for running DOS/Win3.1
Not Win95

All you need/ed to do is upgrade the cpu on the SX(genereraly an SX25 on IBMs) which was usually just a matter of swapping out the cpu or fitting a so called 487 in the extra socket(maybe a jumper change) and possibly ram. The DX was totally adequate of coping with Windows 95 RTM and running Dos/win 3.1 software under it.

All you need/ed to do is upgrade the cpu and possibly ram.

Yes, In 1995 I was enrolled in computer education and the Pentium was being used by over 50% of all NEW computers being sold at the time

Win95 was more of a Pentium CPU era.
The 486 was more of a DOS/Win3x era.

A system is what you make of it. I run OS/2 v3 (released in 1994) in one of my 486s. Seeing DRDos 6 or MSDos boot in a window while running it's native Dos in a window and as well an OS/2 command session again in a window and rumming a couple of BBS nodes on it while playing chess is pure geek heaven. Restricting capabilities to one particular era or set of programs for something like a 32-bit system is just, shall we say, a bit anal. But that's just my opinion. Hell Linus created the initial linux core on a 386 and look how that went.

Goodness only 50%. From previous posts by other members here you would've thought 486s were dropped as soon as the P60s were released 1993.

I've never used that tool, I can't evaluate it. You can do it please

Most of the 1993-94 era 486 PS/1 2155s have onboard Cirrus Logic 542x VLB video and local bus IDE.

I ran windows 95 RTM on a 386-DX40 with 8gig RAM for a while. It was perfectly usable, though definitely not great.

I have the IBM PS/1 running win95b now. With Original Intel 486dx2-50 CPU, 16mb of ram, 256kb cache and 730mb IBM hard-drive.
And it performs okay but not the best. A pentium PC would perform better.

But if in 1993 this 486dx2-50 setup would have costs close to $4000
This IBM PS/1 computer is dated late 1994. and was priced at $2,699 for the base model.

Between 1992-1995 IBMs were a serious ripoff. They still pretended their machines were relevant and charged twice as the competition for basically the same thing.

No kidding. Nobody really bought Pentiums until 1995. Only organisations and uninformed rich jerks bought Socket4 before the P54C came out. I remember 1995 as the year that normies started buying DX2-66 in volume. The 486 was definitely still a thing 1995. Windows 95 effectively killed off the 486. It was one of the first must have software that made the 486 feel like a slow piece of shit. I switched back to 3.x and tried to ignore it, but that became hard when the industry focused on software for 95 and eventually gave up on 3.x. Windows 95 was only really okay on a DX4 or 5x86 if you had 16MB of RAM. I know some people claim that a DX-33 with 8MB is good enough, but those people are masochists.

I stuck with my 486 up untill someone gave me a good deal on an IBM PC300GL mini tower with Windows 98FE on. A Celery 400. Still have it too. So you could say I missed the "whole start me up thing". By then I was looking at alternatives and got the OS collectors bug. To me computer a tool not a satus symble. Wasn't a gamer so didn't need megagigas of stuff to slip in the system. I could share a ppp connection with two other computers over 2BaseT running from the bed room to the lounge to the conservatory. Old '50s houses are great for that thought of thing. 😀
