HP48GX Meta Kernel



#2

Hello,

I am trying to install Meta Kernel as downloaded from hpcalc.org. The setup document indicates that the name of program MKRAM.KER needs to be on the stack while the program RECV.KER is executed. I have loaded both programs as variables. However, when I execute RECV.KER as prescribed, I get an error "Vider le port 0!". Am I missing a step, or do I somehow need to empty port 0 while still being able to execute the setup program? Any help you are willing to offer would be greatly appreciated!

Hello Jeff!
Here is a brief "how-to" for installing the MetaKernel onto an HP48GX (I tried it on my 48GX and it always worked fine):
1 > put a RAM card into slot 1 of the 48GX, with the calc switched off
2 > switch on the calc
3 > Initialize the RAM card by pressing LeftShift+LIBRARY / NEXT / PINIT (see page 28-14 of the HP 48 G Series User's Guide)
4 > Merge the memory in slot 1 by pressing LeftShift+LIBRARY / MERG (see page 28-16 of the HP 48 G Series User's Guide)
5 > Connect the cable first to the PC and then to the calc
6 > On the 48 GX press RightShift+I/O
7 > Choose "Transfer" on the menu and press the "OK" softkey
8 > Set the parameters as follows:
PORT: Wire
TYPE: Kermit
NAME: “void”
FMT: Bin
XLAT: Newl
CHK: 3
BAUD: 9600
PARITY: None
OVRW: no flag
9 > Push the "NEXT" softkey
10 > push the "OK" softkey
11 > Press RightShift+RightArrow: on the display of the 48GX you'll see the message "Awaiting Server Cmd"
12 > start the HP Connectivity Kit (version 3.0r4) on the PC
13 > In the PC window select the directory where the two files of the MetaKernel are stored
14 > Drag-and-drop the file RECV.KER on the HOME directory of the 48GX
15 > The transfer starts - on the display of the 48GX you can read the message
"Receiving RECV.KER
Packet # ...."
16 > The calc will receive about 10 packets for the file RECV.KER (average transfer rate = 150 cps)
17 > When the transfer ends, on the display of the 48GX the message "Awaiting Server Cmd" is shown again
18 > Drag-and-drop the file MKRAM.KER on the HOME directory of the 48GX
19 > The transfer starts - on the display of the 48GX you can read the message
"Receiving MKRAM.KER
Packet # ...."
20 > The calc will receive about 2099 packets for the file RECV.KER (average transfer rate = 150 cps)
21 > When the transfer ends, on the display of the 48GX the message "Awaiting Server Cmd" is shown again
22 > press "ON" to exit the transfer mode on the 48GX
23 > digit 'MKRAM.KER' on the 48GX (remember to enter the first and the last tick: '...')
24 > Press the softkey corrsponding to the RECV.KER program
25 > Within a few seconds the MetaKernel will be installed on the calc


Hope this helps.

Best regards.

Thanks Giancarlo!

After reading your response, I found that the way I downloaded the RECV.KER and MKRAM.KER files also included downloading the HP48 Server. This server library remained in port 0, which is why the RECV.KER execution bombed. After purging the server library from port 0, the command worked as described. I now have Meta Kernel installed! Thanks again for your response!

Take care,

Jeff

Jeff,

I've been reading the information by knowledgeable people

in this forum since a long time now, and I was delighted

by what I was able to learn.

I'm really glad to have been helpful to somebody else, once in a while!

Best regards.

Giancarlo
