The PS/1 archive and updates

I’ve reorganized my material and updated all filenames in the pages under the “downloads” section.

Italian preloaded software for the 2011 has also been cleaned from extraneous files and the HDD image and backup diskettes have been recreated.

Other previously published content has not been modified.

The complete IBM PS/1 archive, kept updated with new material:
https://www.mediafire.com/folder/2tuxpmsn1exyu/IBM_PS1_archive

The whole archive as a single compressed file, updated 2 jan. 2022: IBM_PS1_archive_20220102.7z

Please inform me of any broken link.

PS/1 2011 patched ROMBIOS for XTIDE Universal BIOS

The standard 2011 ROMBIOS is not compatible with current versions of the XTIDE Universal BIOS.

The last version of XTIDE compatible with the PS/1 2011 is v1.1.5

Starting with v2, XTIDE switched to a late initialization mode, which delays any initialization after the system BIOS calls INT 19h to boot. The problem with the 2011 is that it does not use INT 19h to boot.

The following patched version of the PS/1 2011 ROMBIOS has been modified to use INT 19h if XTIDE v.2+ is installed in the system.

NOTE: it’s for non-US models only.

Read the included readme for instructions.

PS/1 2011 FR ROM

IBM PS/1 model 2011 ROM, French version.

This is a dump from a PS/1 sold in Belgium and it’s in french. At this moment I’m not sure if it’s any different from the ROM of 2011’s sold in France (donations are welcome!). I was able to verify that PS/1 2011 sold in Belgique and France have the same ROM (thanks Laurent!)
