Hi, Yes, it is, and i have re-done the testings to see if it is true, and it is. It's a pc with Sempron 2800+ (1.6GHz), HDD1 sata1 , HDD2 sata2, RAM 2GB. In my case, just because of the RAM=2GB, i decided that 768MB is enough and it was. HDD1 working o.s.(winxp). Always i use GParted to get my partition before to install any kind of operating system. Just use it and you'll never be disappointed.(how to use it, you can find a proper tutorial on the web). And GParted uses align to sectors, first sector 2048. If you make the partition during the install of win xp, you'll get aling to cylinder first sector=63, see the foto1. Using gParted, see the foto2, you get align to sectors first sector=2048. (some fotos for gParted: foto3, 4 and 5). Install the win XP and configure it to get the most of it, i'am not the right person to guide you over this process. (anyway get rid of useless services and process, turn off pagefile, etc. DURING the time of using Win Toolkit). HDD2 formatted NTFS "align to cylinder" first sector=63 Using the win xp wizard for making the partition, you get a partition align to cylinder first sector=63 see foto6 and 7. HDD2 formatted NTFS "align to sectors" first sector=2048 Using Bootice you can choose align to sectors first sector=2048. See foto8 and 9. I don't remember the home page of Bootice, but you can downloaded this Win Setup_1_0_beta8.7z and find it inside the folder "win setup\files\tools\" The logs are deleted now, if i have time i'll do the testings again and i'll post the logs, fotos and settings for Win Toolkit. Win Toolkit has to integrate only the post sp1 updates, .msu kind not converted to .cab,i don't use at all any kind of McRip and KUC, i have my own downloaded updates using WUD and manual downloading from the MS servers. They are about 110 for these days. Addons=0, etc=0. Imortant: Before you start the Win Toolkit better if you defragg the HDD's. Also, each time i make once again the test i prefer to re-formatt the partition of the HDD2. If i missed something, just let me know... Anyway, now with the new version of Win Toolkit(beta, sorry i don't know if it is ok to use it, i didn't asked for permission), i use an other technique just for the ramdisks, i think it's better. Time having, i'll will post it. Regards, cmos. l.e.spelling, sorry for my @$&_english :-(
