Below is a list of files necessary to create a 3.5" Boot Disk for OS/2 GA with HPFS support. Sorry but HPFS.IFS makes it too large for 5.25" drives.

Copy sysinstx.com from the Install Disk and run this to copy the hidden file OS2BOOT from your hard drive to a Formatted 1.4 meg floppy. Copy the other files from the appropriate disk to create the boot disk.  OS2BOOT         1099   Created on boot disk by sysinstx.com OS2KRNL       716044   Copy OS2KRNLI from Install Disk and rename. OS2LDR         32256   Copy from Install Disk. OS2LDR  MSG     8440   Copy from Install Disk. SYSINST1 EXE    4224   All other Files Copied from Disk One. CMD     EXE    87552 CONFIG  SYS      379 ANSICALL DLL     438 BKSCALLS DLL     401 BMSCALLS DLL     398 BVHINIT DLL     9203 BVSCALLS DLL     454 CLOCK01 SYS     3666 COUNTRY SYS    24604 DOS     SYS     1142 DOSCALL1 DLL   87884 HARDERR EXE    14436 IBM1FLPY ADD   24026 IBM1S506 ADD   12908 IBMINT13 I13    9564 KBD01   SYS    29013 KBDCALLS DLL     858 KEYBOARD DCP    5177 MOUCALLS DLL    1010 MSG     DLL      477 NAMPIPES DLL     711 NLS     DLL      465 OS2CHAR DLL    56320 OS2DASD DMD    31994 PRINT01 SYS     8934   Only needed if you want to be able to print. QUECALLS DLL   14994 SCREEN01 SYS    1441 SYSLEVEL OS2     169 VIOCALLS DLL    1825 SESMGR  DLL    31256 NPXEMLTR DLL   25280 HPFS    IFS   125466 36 file(s)   1373409 bytes used 70144 bytes free  My CONFIG.SYS files is as follows:  ifs=hpfs.ifs /c:4 buffers=32 iopl=yes memman=noswap protshell=sysinst1.exe set os2_shell=cmd.exe diskcache=64,LW protectonly=yes libpath=.;\; pauseonerror=no codepage=850 devinfo=kbd,us,keyboard.dcp device=\dos.sys set path=.;\; set dpath=\; set keys=on REM leave out the line below if you do not need to print basedev=print01.sys basedev=ibm1flpy.add basedev=ibm1s506.add basedev=ibmint13.i13 basedev=os2dasd.dmd  Adding HPFS.IFS allows you to view and manipulate High Performance File System drives.

To use CHKDSK.COM against these drives format a second floppy and copy CHKDSK.COM and UHPFS.DLL to the disk. CHKDSK loads UHPFS.DLL when it gives the message "The HPFS file system program has been started". You could also add CD support to the boot disk by including CDFS.IFS to your boot disk and adding the appropriate IFS= statement to the config.sys. If you do this add UCDFS.DLL to your second "utility" disk for chkdsk, format, etc. to load.
