ISA ROM initialization problem
Awhile back, I was testing iPXE ne2k_isa images for use with an RTL8019AS-based ISA PnP NIC. This is a challenge, as you really need at least 64k for iPXE, but that's the outside boot ROM limit for many ISA NICs. I recently came back to this project and synced my branch from master before continuing.
The .dsk image worked fine when put on a floppy disk, but the .rom image won't initialize from the BROM chip. The card is jumpered for a 64kB ROM at address D000. So I rebuilt with Code: DEBUG=init:3,ne2k_isa:3 Code: iPXE starting execution...1B101B10 000D11B4 0001AD5C Where should I go from here, if it's not able to get into the Init code? I had previously suspected it's not decompressing the image properly, and I think that still could be the case. TIA |
