    @Goodmaneuver Is there a special reason why you use Media Player Classic - Home Cinema vs 1.4.2499.0?

    Thanks a lot. Indeed, the second dialog wasn't typo-proof. I made corrections to the batch-files above.

    Today I tested my rd2hdf16.g4b without the --unsafe-boot switch. Doesn't make any difference, rdbase still has to be set to a minimum of 37MB, or DISKEDIT will find somewhere in (hd0) the content of the batchfile, together with the command-line of the batchfile. *Somehow* Grub4Dos needs more than 32MB for safe operation with my g4b batch-file.

    In that case your custom.inf doesn't seem to work. I tested Jaclaz suggestion to edit MSDISP.INF, worked for me, but tested on Win98se only. If you like you can try following. Remove the lines to your custom.inf from MSBATCH.INF, but maintain [System]. Take a copy of MSDISP.INF and edit in the way I will show you. Copy the edited MSDISP.INF together with VBEMP.DRV and VBE.VXD to the folder where your CAB's are (maybe you must make a new ISO?) Install Windows again.

    I have finished my batchfile for FAT32 (to make a Grub4Dos Ramdrive, map it to a harddrive and format with FAT32). In comparison with my FAT16 batchfile: skipped mapping of first attached real hdd to last hd (if needed set elsewhere). Further: Asked inputs time limited. rdbase set higher to avoid problems during execution of the g4b-batchfile. Sectors per FAT no longer a constant, but depend on disksize. Set to the same amount as FORMAT.EXE would set them. Writing backup of Bootsectors. Choice to write valid Volume Label to first Directory entry (compatible with MS-DOS7.1, Win98se AND with Grub4Dos vol --write). ---------------------------------------------------------------------------------------------------------------------------------------------- rd2hdf32.g4b ---------------------------------------------------------------------------------------------------------------------------------------------- !BAT # Make FAT32 hdd-image: active first partition; range 33-3400 MB debug off set /a SIZE=%1 if %SIZE%=="" && goto :validate if %SIZE%>=3401 && goto :validate if %SIZE%<=32 && goto :validate goto :makeimg :asksize echo Disk size in range 33-3400, integer numbers only echo Actual image size will be adjusted to cylinder boundaries! set /a SIZE= set /p:60 /a SIZE=Enter disk size and press ENTER in 60 seconds: if %SIZE%=="" && goto :validate if %SIZE%>=3401 && goto :validate if %SIZE%<=32 && goto :validate goto :makeimg :validate echo Input is not a valid number, try again set /p:60 CONTINUE=Try again? choose Y or N and press ENTER: if /I "%CONTINUE%"=="Y" && goto :asksize goto :eof :makeimg if %SIZE%<=3400 && set /a heads=128 if %SIZE%<=2016 && set /a heads=64 if %SIZE%<=1008 && set /a heads=32 if %SIZE%<=504 && set /a heads=16 set /a sectmax=%SIZE% * 2048 set /a sectrack=63 set /a secthidd=63 set /a cylinder=%sectmax% / %heads% / %sectrack% set /a sectbal=%cylinder% * %heads% * %sectrack% set /a sectpart=%sectbal% - %secthidd% set /a rdsize=%sectbal% * 512 # Set rdbase >=50MB.

Update: I found a small bug if less than 11 characters where given in the Volume Label part. Windows SCANDSKW.EXE didn't like this and wrote as correction a "-" for an empty place. I cured this to pre-write ten "20"'s instead of zero's to the first directory entry ("E5" is not changed, is needed for compatibility with Grub4Dos vol --write. Otherwise "error 15: File not found" if the first directory entry is empty). I added a disk size command-line argument. Use: rd2hdf32.g4b SIZE (in MB). Example: rd2hdf32.g4b 400 will make (hd0,0) 400MB in memory, FAT32 formatted. Size is rounded down to cylinder boundaries. Update 2 --rd-base set to 50MB; set max SIZE to 3400 (MB); edited one #comment.

    Has to do with the so called "System Arena" in win9x memory architecture. Since vcache is using it too, sometimes smalller is better. See https://www.pc-experience.de/wbb2/thread.php?threadid=1903 In *some* win95 KB (cannot find it anymore) MaxFileCache=8192 is mentioned as value to solve stability problems. If MinFileCache is not set, MaxFileCache should > 1/24 of memory (RLoew's Rule of Thumb - he didn't mention MinFileCache needed). According to my experimental findings lower values are possible, but always MinFileCache <= MaxFileCache. In my "Smartdrive Revisited"-investigations I found a vcache of value 1024 (=1MB) as "best" (not related to win98 Setup, but to some problems using a win3.1 HD audio driver). In my USB-project the extreme low vcache value has especially the purpose to minimize System Arena footprint if Win98se is running on a Memdrive. My standard Win98se Setup values, set in SYSTEM.INI after copying files: [386Enh] MaxPhysPage=20000 ConservativeSwapfileUsage=1 DMABufferSize=64 [vcache] MinFileCache=1024 MaxFileCache=1024

    Hm, the Bios Setup of your GA board doesn't look very promising. I assume you run the SATA ssd in IDE mode. And what about the extreme low vcache settings I mentioned in my USB project? If *something* is mapped in memory you can try Jack Ellis XMGR.SYS instead of HIMEMX.EXE (who gave you already an extra reboot).

    Sometimes Opera's kiosk mode is helpfull in case of msfn. Looks same as in my Android smartphone.

    I agree that memory problem can be unsolvable. Once I tried (from USB drive) MS-DOS7.1 on a Gigabyte board, if I remember well a Z170 species. Didn't work! I am a happy user of my 2010 Asrock 960GM-GS3 AM3+ board (with FX 6100/DDR3 1600), compatible with everything except Win98se ACPI.

    I should have written "install W9x without PCI-bus first, if succesfull try your luck with wizard New Hardware." After installing the PCI bus and reboot once you will have full control which Device to install and which not. Do not reboot after installing PCI devices, first check Device Manager (view Connection) for double entrances. Especially the non-PCI VGA device should be deleted manually before reboot. But you have already red my "Exploring SETUP /P I;S=detectbus......"-Members project. The /P S= switch is very badly documented. All entrances in MSDET.INF can be used to skip during installation (seperated with , ).

    You should try SETUP /P I;S=detectbus to install W9x without PCI-bus.

    I know about set /a and set /A, but I am not so far with the "%" and" ~%"-"thing". I am happy with my simple if-statement in the case you mentioned, but I am afraid I will have to use the more advanced methods I want to read out Number of Heads from the MBR, adding 1 and convert to \X..-byte values to be able to use write to write the value directly in the Boot sector. Not to speak from Sectors/track with 6-bits value in the mixed Cylinder-Sectors/track-byte. That's the main reason I choose one batch file. It´s partition alignment to cylinders as far as I understand this subject (see error 108 in https://www.win.tue.nl/~aeb/partitions/partition_types-2.html ). I don´t think it´s a bug and it should only be a problem in very rare cases AND if one wants to use Partition Magic (in my case for error check, the program cannot be used to partition Grub4Dos disk in memory because of the stupid reboot feature). In following text I compare the output of Partinfo. The first is the example you was so kind to give me in your post of januari 31. Th second is the result of repartitioning the same drive in memory with Fdisk. Ther third is the output of my batch. The maximum disksize is 256 MB, like in your example.

    After the problems with the DOSBox images, I used Jaclaz' guidelines to make a Hard disk from a Grub4Dos Ramdrive. It seems that Partnew doesn't write to cylinder boundaries. Although Windows 98SE Setup doesn't complain, my MS-DOS util's do. So I wrote a correction in a Grub4Dos batch file. Since the Grub Util FAT seems only good for floppies, I wrote some batch lines to format the drive to FAT16 too. It's al in ONE file. Will make and format ALWAYS (hd0,0), first attached real hdd will be mapped to last hd. --------------------------------------------------------------------------------------------------------------------------- rd2hdf16.g4b --------------------------------------------------------------------------------------------------------------------------- !BAT # Make FAT16 hdd-image: active first partition; range 33-2047 MB debug off set /a SIZE=%1 if %SIZE%=="" && goto :validate if %SIZE%>=2048 && goto :validate if %SIZE%<=32 && goto :validate goto :makeimg :asksize set /a SIZE= echo Disk size in range 33-2047, integer numbers only echo Actual image size will be adjusted to cylinder boundaries! set /p:60 /a SIZE=Enter disk size and press ENTER in 60 seconds: if %SIZE%=="" && goto :validate if %SIZE%>=2048 && goto :validate if %SIZE%<=32 && goto :validate goto :makeimg :validate echo Input is not a valid number, try again set /p:60 CONTINUE=Try again? choose Y or N and press ENTER: if /I "%CONTINUE%"=="Y" && goto :asksize goto :eof :makeimg if %SIZE%<=2047 && set /a heads=128 if %SIZE%<=2016 && set /a heads=64 if %SIZE%<=1008 && set /a heads=32 if %SIZE%<=504 && set /a heads=16 set /a sectmax=%SIZE% * 2048 set /a sectrack=63 set /a secthidd=63 set /a cylinder=%sectmax% / %heads% / %sectrack% set /a sectbal=%cylinder% * %heads% * %sectrack% set /a sectpart=%sectbal% - %secthidd% set /a rdsize=%sectbal% * 512 # Set rdbase >=50MB.

I even managed to download Kernelex 4.5.2 from Sourceforge. But javascript is to old (should be disabled). Websites can only be viewed in a sort of elementary html user mode.

    If the printer needs USB 2.0 an Enhanced USB controller driver is needed anyway. Personally I prefer NUSB33. Showed Device Manager an Unknown USB Device? About your USB-printer: a seperate driver should be needed. Can't help you further, I have used a HP Laserjet 4 Plus (LPT; duplex; 1993!) during 13 years, until a few weeks ago. Repair seems to be impossible

    What kind of USB devices (or controllers?) did you mean?
  19. deomsh
    Nice tools, I have just tested them. Thnx I have run all the tests, anything goes as soon the USB-FDD is accessed once. Even ls (fd0)/pleasels.me did the trick, grub gave error "file not found" (will only work in menu.lst with errorcheck off). Also map the image again in the same Grub-session (in earlier drafts of Part 8½ I mapped first a floppy image right before hdd-512mb-img.gz - but thought it would be to experimental for my menu.lst). I also tested loading hdd-512mb-img-gz from a real floppy after booting form USB-FDD. Exactly the same story. Without earlier drive access by Grub4Dos always the "bad" 0x0E mapping. As soon there has been "real floppy" drive access (nice: one can hear it) everything is fine with the 0x06 mapping.

I tested the ls-command as you asked, no difference. Always the "good" mapping (although unbalanced, as you teached me). "Timing" was just an idea. The whole problem is *somehow* USB-FDD related. If I boot from USB-FDD, but the image is located on an USB-HDD usually the Memdrive has Partition ID 0x06. If I boot from USB-HDD, but the image is located on an USB-FDD things are much worse. Sometimes I first have to map the USB-FDD before Grub4Dos finds the image! I have used used Partition Magic many years, always complaining about this "thing". But the corrections the program wanted usual make things worse. I have to investigate the CHS/LBA balancing further, because I never succeeded to boot from Winimage IMA-images with MBR, mapped to a Memdrive. IMA-images without MBR gave no problem, but had always the Grub4Dos MBR with Partition ID 0x0E (which as such is not a problem in case of Win9x).

    is a "hardcoded/absolute" path to the image, this one: is a "relative" path. Both are "wrong" (theorically/philosophically), what happens with the "right" one?: Or there are other differences that I missed?

    I am very grateful for this, your idea to map the Grub4Dos ramdrive to a harddrive is very promising. I am still busy testing. It appears the bootsector is write protected, but mapping with --unsafe-boot did the trick. The FAT module gives still the wrong mediabyte (F0 instead of F8), but can be useful because of the possibility to write an uuid and/or an volume to the drive for easier identification. No problem to install Windows 98se on the drive after running SCANDISK and SYS! I tried other --heads=64/32/16 to change the geometry of the Memdrive while mapping the Dosbox image, but that didn't make any difference. But I think I found how the "bad" Memdrive is different from the "good" one. Thanks to the homework you gave me, I became more aware of the hex representation of MBR's, bootsectors and starting bytes of the FAT.

checked with HxD. The MBR of the "bad" 0E-mapping is the one that Grub4Dos generates while mapping a partition to a Memdrive. Somehow it seems that Grub4Dos has find/read/timing problems in case of USB-FDD. With or without real floppy attached made no difference. About the two first commands of the "good mapping": with or without --unsafe-boot made no difference either. I tested the two command chains on three machines with different chipsets, all same results. Also on one machine with the USB-FDD in three different ways formatted.

    Only with USB drivers disabled. See my Windows 98se project, Part I and Part III. I don't possess Windows ME. https://msfn.org/board/topic/180597-exploring-setup-p-isdetectbus-and-grub4dos-8½-times-win98se-on-usb-drive/

    I am afraid there is some misunderstanding. I said following: and: but also: For now I will return to my labarotory to run the tests you gave so friendly. BTW in the meantime I found out that I can open the uncompressed DosBox images with HxD, so I hopefully I can deliver some more info.

    Grub4Dos "asked" me for it, else the image won't load. I examined the source image more closely. The DosBox image seems to have partition table, exactly the same as first cat --hex below.
