twolfson 0 Posted January 28, 2002 I just picked up a used IBM PL300 desktop and I'm having problems setting it up. After fdisk and formating the HD I loaded Win98SE. The load went OK but when it was done there was a message box telling me that the unit is operating in dos compatability mode and my master boot record may have been modified. I tried rumming fdisk /mbr but that didn't change anything. Other symptoms: windows recognizes the ide master controller but states that the primary and secondary controllers aren't working correctly. also the only way I could get the CDrom to work was to load command lines in my autoexec.bat and config. sys files. Any thoughts will be appreciated. Tia, Terry Share this post Link to post
Guest Posted January 31, 2002 Run msconfig, choose advanced, and make sure the "Force compatibility mode access" isn't checked. Share this post Link to post

insaNity 0 Posted February 5, 2002 For future reference, it was more than likely that you needed to install the busmaster IDE drivers. you could get them through the IBM website or perhaps direct from the chipset/io manufacturers Share this post Link to post
deeman 0 Posted April 3, 2002 Future reference, all IBM laptops come with a cd called a 'recovery cd' which contains Windows 9x, and all of the relevent drivers. Pop the cd in, and 15 minutes later you have a complete and ready to go laptop (no install prompts required) It's crucial to run that cd as their drivers are so difficult to get and specific with each PC/laptop, and of course will produce a bunch of problems if not loaded. The cd's are available from between $20-70 from IBM. Daniel. Share this post Link to post

Chunny 0 Posted July 27, 2002 On my brothers duron , If install the via 4 in 1 drivers, it puts his harddrives on dos compat mode. I have no idea, so I just put XP on there Share this post Link to post
