April 29, 200521 yr Io.sys from Q311561 reduced by 100KB.I've removed DOS configuration manager and standard boot logo.logo.sys still can be used.It can be interesting.WINBOOT.zip
September 6, 200817 yr I've removed DOS configuration manager and standard boot logo.What is that? F8 startup menu?
September 29, 200817 yr to Marius '95No it's the integrated memory manager that has been removed (automatically used by Win98 (some kind of trick to say that win98 is not DOS...)).tested, work great, replace the io.sys file on my bootdisk...
September 29, 200817 yr No it's the integrated memory manager that has been removed (automatically used by Win98 (some kind of trick to say that win98 is not DOS...)).Isn't this only true for Windows ME? AFAIK, Windows 98 doesn't have a memory manager integrated into its kernel.

AFAIK, Windows 98 doesn't have a memory manager integrated into its kernel.Of course you are right, alexanrs! Tihiy has removed the integrated the DOS part of DWCFGMG (DOS and Windows Plug and Play Configuration Manager), which is redundant, because its supreceeded by CONFIGMG.VxD when starting Win 9x. See also the attached text (from 1994, when it was standalone).DWCFGMG.TXT
September 30, 200817 yr Never knew that that was integrated into IO.SYS.For those with Plug'n'play addon cards that do not want to allow the bios to handle it all by itself, is there a way to activate this in a non-modified IO.SYS or it was left there de-activated?
October 5, 200817 yr Just tried this. Unfortunately on my system, it will boot Windows in fallback video mode (640*480*16 colors), with a message saying the videocard couldn't be configured; and even though windoze offers to change the display mode, it will /force reboot/ after doing so : upon reboot, go back to square one !This goes to prove that the DOS part of config manager may be useful on some systems...I'll still keep Tihyi's reduced IO.SYS, will be great for booting DOS 7 from floppys.-- Ninho

You rock! Reporting the issues of modded programs is of fundamental importance, and helps a lot when troubleshooting our systems!
October 12, 200817 yr Hi.For years, I am looking for details about: IO.sys logo compression.Now, it seems to be that Tihiy could have the solution.Comparing Tihiy's reduced io.sys with the original io.sys there are following differences:a.) Different header b.) differences at: 0x136C2, 0x136D5, 0x136D6 c.) additional data at 0x1E010 inside the original io.sys.At 0x1E010 there are following bytes:7D8C0020445300000A6D8A0B6F400081B549C0288AA100813C0A0221862270C4C094B80009618C0863334420FD090A10415080108202C410146088A000530405182328C01C41010A090A50495080528202D41214E09AA000E70405B827282002410171080AA84450402D8202EA11149093A080DE040574273802991B838C0D43Is 7D 8C 00 20 ... a header for a Microsoft compression format (ms cab, ms compress/expand, lz77, lzxx)?Is the splash screen / logo inside the original io.sys compressed at all?How to extract/uncompress the logo data in Win95/98/ME's io.sys?

October 12, 200817 yr Because DOS manager has been removed, ye need the following line in MSDOS.SYS[Options]SystemReg=0This disables DOS looking for system registry entries, and lets windows use a different way of doing what is needed.
December 7, 200817 yr is it possibile to add this patch to this patched file herehttp://www.msfn.org/board/index.php?showto...hl=patch+io.sys
