@Tomcat, two things regarding the above problem. (1) Slipstreaming a CHT system shows up as "XP SP1 Traditional" instead of "XP SP1 Chinese Traditional". Is this intentional? (2) ctpooon (above) seems to have slipstreamed SP2 using HFSLIP (WindowsXP-KB835935-SP2-CHT.exe). However, HFSLIP does not appear to have recognized this. Could this have to do with the ntfs.sys error or is that a whole other problem? @ctpooon, you are not paying attention to directions very well! You are slipstreaming XP SP1. If you use Tomcat's list, you MUST check the "Service Pack 1a" box. If you read the_guy's post above, as well as the directions on Tomcat's page, KB900325 is for XP Media Center Edition. You do not need it for your OS! If you want to include the Windows Media Player 9/10 codecs, you need to extract wmfdist95.exe out of the KB900325 hotfix. Do not worry about this. This is only if you successfully installed the HFSLIPed system.Generally, I would not recommend including updates for two different languages. Sometimes, this messes up the OS. Now, please don't come back here until you sort out your hotfixes (as above). HFSLIP is not for people who don't read simple directions.
