1.2gb is alot of free space. Try a more realistic value for that era.

Thanks for your reply!

I also tried different values (50 mb, 100mb) but it didn't work.

Forgot to add my CD Mount command - maybe it has to do something with the issue:

mount D K:\ -t cdrom -ioctl

Any other idea? Is there maybe any mount command I could try?

Dosbox have the trouble with the -freesize 512+. So - use something like "mount c d:\dosbox -freesize 500".

Doesn't work either.

I just tried with Dosbox 0.70. There it works. Attached you find my 0.74 Config file - maybe I made a mistake there.

Please try a clean build of the most recent SVN source available here. Some changes were made regarding the drive characteristics reported for free space queries; mostly to work around bugs in some installers.

Hi,

this didn't solve the issue.

If you are interested in the Setup File please let me know.

Attached you find a zip File containing the install.exe.

The Message
"Deine Festplatte hat nicht genügend freien Speicher für Hugo..." means that the disk doesn't have enough free space to install.

Thanks for your help!!

The installer checks the 8-character BIOS date string at F000:FFF5, and if it finds a reasonable date it performs an additional drive check with INT 13. DOSBox has a date string in 0.73 and later, so earlier versions managed to avoid the drive check.

The drive check is a call to INT 13/04 (verify disk sectors) on the MBR. DOSBox does not set the carry flag to indicate an error, but it does not clear AH, so the installer thinks there's a problem with the drive and won't use it.

Doing something similar to what is done for the Inherit The Earth cdrom installer works around the issue. Note that the high bit of the drive number is not set (i.e. for drive C, DL==0x02), as would be expected:

1     case 0x04: /* Verify sectors */
2         if (reg_al==0) {
3             reg_ah = 0x01;
4             CALLBACK_SCF(true);
5             return CBRET_NONE;
6         }
7+        if (!any_images) {
8+            // Hugo (uses it as disk test)
9+            if ((reg_dl>1) && (reg_dl<DOS_DRIVES) && (Drives[reg_dl]) && (reg_dh==0) && ((reg_cl&0x3f)==1)) {
10+                reg_ah = 0;
11+                CALLBACK_SCF(false);
12+                return CBRET_NONE;
13+            }
14+        }
15         if(driveInactive(drivenum)) return CBRET_NONE;

Thanks for the explanation. But it doesn't help me too much. Where do I have to insert these lines?

The changes are to bios_disk.cpp; however, do you really need to go through the exercise of compiling DOSBox? Simply use a version prior to 0.73 to install the game, and the current version to play. If a similar check is done by the game itself, then I guess you'll also need to use the older version to play.

Thanks for your reply. Recompiling is not what I'd like to do 😉

I've got another 2 setup files that don't work. You find the one attached below and the other here:
http://www.share-online.biz/dl/YXC3F6MLOV8

The password is "hugo"

These two files don't work in older dosbox versions. Maybe you can give me a hint. Thanks!

It seems they all use the same disk test, but hugo5 skips it if there's no BIOS date string. Not sure why it looks for the date... I guess because INT 13 is a BIOS function, and not having a date could mean the BIOS has been replaced with UMBs or some such.

Anyway, here is a TSR program that should satisfy the disk check these installers use. Run it inside DOSBox before running the installers. See if it also needs to be resident in memory when playing the game, or just for installing.

Thats great! Thanks a lot!

Think I will add a log message to that if I commit it.

It seems this fix was never commited, as I had the same problem with the game in the current SVN today. However, ripsaw8080s TSR tool still works great, thanks for that!
