Was thinking of getting a 486 to run os/2 warp 4.52. However on the usual sites they are quite expensive. Pentiums are much more reasonable. What type pentium and how much (max) memory will os/2 be able to run?

I have an IBM PS/1 TYPE 2121. It came with a 386SX chip, 2 Mb of Ram and a 42 Mb hard drive. Over the years I've upgraded it to a 486SX with a Cyrix chip, 6 Mb of memory and various hard drives. I also bought an adapter unit with 3 ISA slots and the 5.25" floppy drive unit. I also managed to find …

Just an update. I installed the 512MB DOM in the PS/1 and it was recognized in the bios. Then FDISK, FORMAT, SYS, with Ibm dos 4. I restored DOS 4 from my backup disks and then upgraded to 6.22. I then installed Windows for workgroups. The Cyrix chip driver was next. Then the TCP/IP driver. I'm now …

Try SYS C: from the floppy drive. Format C:/s doesn't always give the desired results. While you're there, FDISK/MBR won't hurt either. .... OK. I shall try those. EDIT: No luck. The DOM doesn't seem to hold the FDISK settings. The set active flag disappears and file system shows unknown. I'll try …

I formatted the 512 Mb in the 486 with the /s flag (DOS 6.22). Booting from a floppy I can access the DOM and see the files. However the system won't boot from the DOM. The SET active flag is set under FDISK. Any ideas?

There is indeed. I think it came out after the PS/2. Mine is a TYPE 2121. 386sx, 2Mb ram, 40 Mb hard drive. . I had to buy an adapter unit to get ISA slots

I'm up and running with Windows 95 on the 486. I put MS-DOS 6.22 on the 486 and used my backpack CD ROM drive to install Windows 95. I didn't need the Setup floppy which I used DiskWrite to write the image to the floppy. The weak link in all of this is the USB floppy drive. So to get the Win 95 …

1) Can the 486 boot from any other floppy disk? 2) How do you "expand" the image to the disk? I'll check the floppy drive later. The PC is in the attic and I'm a bit lazy today. I have a few others that I never used so I'll be able to experiment. I have Win 98 that came with a Dell PC that I no …

I have a PCd-4H 486sx with overdrive chip. I also have a Win 95 floppy image. The image boots under VirtualBox but when I expand it to a floppy it won't boot on the PC. What am I doing wrong? I have the original floppy disk that came with the Win 95 but it is damaged.
