PCem

It has some kind of NVR and a clock too, the BIOS SETUP (Control+Alt+Esc) has time and date settings and says "Press ENTER-key to store information into SETUP-RAM"

With "roms folder" do you mean one copy on each machine subfolder like c:\pcem\roms\ibmxt\ide_xt.bin and so on?
Try to copy it directly to roms subfolder like c:\pcem\roms\ide_xt.bin to make it available for all machines because it's compatible with many models.

A bit of trial and error helps with those old machines

Last night while looking for another thing I found an original 256KB module from my PCS386SX and it's non parity and 2 chips type too. I was already convinced the store had not returned me those after the upgrade but it was under the bottom flap of a carton box so the other 3 may been lost by the sa...

It's interesting, I never tried non parity modules because my PCS386SX was upgraded when my Olivetti dealer was already making their own generic computers and they fitted 8x1MB Samsung parity SIMMs and really I don't know what it has before. Olivetti OEM modules could be made by Samsung too but I'd ...

Something happened with my Google Drive shares, try to download it again. Non-parity modules have an even number of chips and were used mostly on 68k machines. :arrow: All SIMM's with 3 or 9 chips have parity and should work on any x86 board, at least 256KB and 1MB ones. 4MB and 16MB may be too big ...

Updated Olivetti PCS patches for PCem 14. Because Headland chipset emulation is required this includes also "[Patch] Headland chipset improvement and more machines" by Greatpsycho https://pcem-emulator.co.uk/phpBB3/viewtopic.php?f=4&t=3060&p=11082&hilit=headland#p11082 Current status: PCS 86 don't w...

Yes, all boards have stickers but all them say "PCS286" even on the 286S... other mystery like the USB to IDE interface.

About the PIN 28 I've searched explicitly for any jumper settings related to ALE and BALE at https://stason.org

I've got a set of two spanish disk for Olivetti PCS 86. Disk 1 have MS-DOS 3.30, Disk 2 have some MS-DOS files, a tutorial and a diagnostic utility. I had a friend that had a Olivetti PCS33. It came with DOS 5.0, Windows 3.x (I think it was 3.1, but maybe it was 3.0) and a disk compression utility ...

I found one archived page with Olivetti setup disks and drivers for some models http://web.archive.org/web/19980418135138/http://nssweb.olivetti.za:80/pages/softlib.htm And about IDE PIN 28 'controversy' it was docummented at least on some FIC mainboards: ____________________________________________...

Not really, it died too... Then it was killed in the line of duty :( If you want to know what's using DMA1 you can use Dr. Hardware Sysinfo https://www.majorgeeks.com/files/details/dr_hardware_sysinfo.html it's shareware and you can test almost everything (chipset tests are disabled) for 14 days be...

My PCS now has a 4.1 GB hard disk, and Ontrack Disk Manager does its job just fine. I'm SOOOOO happy I'm really happy to hear that :D - the old HD actually killed my IDE-USB adapter (the SATA port on it is fine). They seem dangerous! The old hard disk finally wins a battle against USB adapters ;) -...

Can you program an EEPROM with the original BIOS? Because they ship an "anonymous" BIOS
Very interesting proyect

It's a clone of the IBM 5150 board so it can be fitted with all the same ROM chips, take a look here for more info: http://www.minuszerodegrees.net/5150/mo ... 50_u33.htm

It seems that IDE PIN 28 was early used for ALE (Address Latch Enable) later for SPSYNC (Spindle Synchronization) and finally for CABLE SELECT. And the drives recognised by the Olivetti PCS can be jumpered for SINGLE DRIVE, MASTER, SLAVE and CABLE SELECT. Then I guess that those drives used on Olive...

PCS 286: Works with a few issues during boot and CMOS setup. Tested with: DOS, Windows 3.1 and some games. During boot it will complain about VGA and Protected Mode, just press F1 to skip. Needs HEADLAND GC101, GC102, GC103 chipset and a few things. PCS 286 S: Works with a few issues during boot an...

:!: I've found by the hard way that those drives with single drive feature will die when connected to USB or SATA converters or even to modern mainboards. :!: I'm not sure if setting them before to MASTER can solve this but I've already lost 3 working drives trying to make backups and after asking ...

Nice to hear that, congratulations! and what a surprise by the way :o I didn't know that, the few times I used it without the riser was booting from HD and with some card fitted on the mainboard slot for testing without conflicting with the other cards or having to remove them from the raiser. Yess,...

:arrow: I must clarify this a little, when I said: As with physical machine BIOS expects some CMOS bytes initialised (using provided NVR image) I meant to set DS1287 (for models using this RTC chip) control registers to proper values (enable RTC oscillator, disable low battery bits and son on) becau...

Welcome, see the private message because it's not very related to PCem development to post here…

* Edited my previous post to add missing "MMX" to CPU type I've tested CL-GD5434 and Diamond Stealth 3D 2000 with (default?) 4MB and with desktop in 16 bit color depth I've played Commandos BEL and BCD for a few minutes with S3 Trio64 with 1MB and it's fine too with full versions of those games, but...

I've this CD-ROM with some SB drivers: https://1drv.ms/u/s!AsfYUL_MlCt-hNRfWrscUt-kVwkTdg (size is about 12MB)
See the readme files to know for what is each one.

Commandos: Behind Enemy Lines
Commandos: Beyond the Call of Duty
Both working on Award 430VX PCI, Pentium MMX 233, CL-GD5434 (also with Diamond Stealth 3D 2000), SB16, Windows 95 C + drivers provided by DirectX 6 setup

When PCem is updated do I have to reinstall all my Windows and DOS systems or there is no problem with version change? Usually you can keep everything but it's a good idea to create a backup of your previous PCem folder and your floppy/zip/hard disc images if those are on another folder before tryi...

[/quote] And yet, I never ever saw the splash screen being drawn from the bottom to the top . Wild guess: different adapters = different drivers = different ways to access the framebuffer? [/quote] In this case VGALOGO.RLE is a standard BMP file (first two bytes are 'BM') and the image on Windows bi...

Well, I've tested the same HD image with PCem with 386DX @ 16 MHz and DOSBox with cpu settings core=normal cputype=386 and PCem appears to be too fast, but according to those videos of 386 computers the 'progressive' splash would happen only on very very slow machines/video cards and PCem display sp...

This could be altered because on Windows 3.x VGALOGO.LGO contains the code to display VGALOGO.RLE and it's not the same code on all drivers/resolutions/versions possibly having different splash effects WIN.COM is not present on setup disks :roll: it's made by joining WIN.CNF + VGALOGO.LGO + VGALOGO....

Nice job, everything works fine again.

Well, I still have the problem with SB16, perhaps am I using some wrong dll? corrupt MSYS2 environment? somewhat missing? :roll: Could anyone with a successful compilation under MSYS2 upload somewhere its pcem.exe + all dll files please? even the full src folder with the good Makefile will be usefu...
