I have just performed a memory upgrade on a 520 STE and would just like a sanity check before I change things around again. I opened up the ST and there are four SIMM sockets, two of which are populated by the 256K SIMM modules, like so :- ------------------------ empty ------------------------ 256K ------------------------ empty ------------------------ 256K I then inserted two 1MB SIMMs in the empty slots and powered on. A report on the memory configuration indicated that I had the grand total of 1MB in the system. I think the reason for this is that the machine does not look at the memory intelligently and assumes that all the SIMMs are the same (ie/ 256K as it is in the first slot) or there is a jumper that I do not know about that selects 1MB or 256K SIMMs. Questions : 1/ Are there any jumpers to change? I did not see any. 2/ If I take out the 256K SIMMs and insert the 1MB SIMMs in their place, will this yield 2MB? I should hope so! 3/ Is there any way of getting these SIMMs to co-habit giving 2� MB of memory? Thanks for any input on this. Gary.

| 1111.1 | 2.5MB is not in the ROM's | PRNSYS::LOMICKAJ | Jeffrey A. Lomicka | Mon Apr 22 1991 18:43 | 10 |
As far as I know, your assumptions are correct, however, 2.5MB is not supported in the STe ROM's, but there is a commonly available autofolder patch that corrects this. I think I saw a version of it on GEnie. It's not large. If you would like, I could try to fetch it next time I log in there. And, yes, you should put the 1MB simms in the place where the original ones were, and you should get 2MB. Hey - how do you get 1MB with only two 256K simms? or was this a 520STe? | |||||

I thought as much. Oh well, looks like I'll just have to make do with 2Mb - (unless the patch will give me 2.5Mb with this config - if you could pull it across Jeff it would be much appreciated) It is on a 520STe that the upgrade is being done, hence the paltry 512K to start with :-( Gary | |||||
| 1111.3 | 2.5MB softwae fix available here | PRNSYS::LOMICKAJ | Jeffrey A. Lomicka | Thu Apr 25 1991 22:39 | 4 |
PRNSYS::USER2:[LOMICKAJ.HOBBY.ST]SIMMFIX2.ARC contains the code that allows you to configure a 2.5MB STe. Let me know if it works for you. It's a STREAM_LF file - VMS ARC will work with it. CVTARC V the file before using Kermit's BIN mode or STRANSF. | |||||
